How to style button for input type=file [duplicate]

How do you style an input type="file" button?
<input type="file" />

You don't need JavaScript for this! Here is a cross-browser solution:
See this example! - It works in Chrome/FF/IE - (IE10/9/8/7)
The best approach would be to have a custom label element with a for attribute attached to a hidden file input element. (The label's for attribute must match the file element's id in order for this to work).
<label for="file-upload" class="custom-file-upload">
Custom Upload
</label>
<input id="file-upload" type="file"/>
As an alternative, you could also just wrap the file input element with a label directly: (example)
<label class="custom-file-upload">
<input type="file"/>
Custom Upload
</label>
In terms of styling, just hide1 the input element using the attribute selector.
input[type="file"] {
display: none;
}
Then all you need to do is style the custom label element. (example).
.custom-file-upload {
border: 1px solid #ccc;
display: inline-block;
padding: 6px 12px;
cursor: pointer;
}
1 - It's worth noting that if you hide the element using display: none, it won't work in IE8 and below. Also be aware of the fact that jQuery validate doesn't validate hidden fields by default. If either of those things are an issue for you, here are two different methods to hide the input (1, 2) that work in these circumstances.

Styling file inputs are notoriously difficult, as most browsers will not change the appearance from either CSS or javascript.
Even the size of the input will not respond to the likes of:
<input type="file" style="width:200px">
Instead, you will need to use the size attribute:
<input type="file" size="60" />
For any styling more sophisticated than that (e.g. changing the look of the browse button) you will need to look at the tricksy approach of overlaying a styled button and input box on top of the native file input. The article already mentioned by rm at www.quirksmode.org/dom/inputfile.html is the best one I've seen.
UPDATE
Although it's difficult to style an <input> tag directly, this is easily possible with the help of a <label> tag. See answer below from #JoshCrozier: https://stackoverflow.com/a/25825731/10128619

follow these steps then you can create custom styles for your file upload form:
this is the simple HTML form(please read the HTML comments I have written here below)
<form action="#type your action here" method="POST" enctype="multipart/form-data">
<div id="yourBtn" style="height: 50px; width: 100px;border: 1px dashed #BBB; cursor:pointer;" onclick="getFile()">Click to upload!</div>
<!-- this is your file input tag, so i hide it!-->
<div style='height: 0px;width:0px; overflow:hidden;'><input id="upfile" type="file" value="upload"/></div>
<!-- here you can have file submit button or you can write a simple script to upload the file automatically-->
<input type="submit" value='submit' >
</form>
then use this simple script to pass the click event to file input tag.
function getFile(){
document.getElementById("upfile").click();
}
Now you can use any type of styling without worrying about how to change default styles.
I know this very well because I have been trying to change the default styles for a month and a half. believe me, it's very hard because different browsers have different upload input tag. So use this one to build your custom file upload forms. Here is the full AUTOMATED UPLOAD code.
function getFile() {
document.getElementById("upfile").click();
}
function sub(obj) {
var file = obj.value;
var fileName = file.split("\\");
document.getElementById("yourBtn").innerHTML = fileName[fileName.length - 1];
document.myForm.submit();
event.preventDefault();
}
#yourBtn {
position: relative;
top: 150px;
font-family: calibri;
width: 150px;
padding: 10px;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border: 1px dashed #BBB;
text-align: center;
background-color: #DDD;
cursor: pointer;
}
<form action="#type your action here" method="POST" enctype="multipart/form-data" name="myForm">
<div id="yourBtn" onclick="getFile()">click to upload a file</div>
<!-- this is your file input tag, so i hide it!-->
<!-- i used the onchange event to fire the form submission-->
<div style='height: 0px;width: 0px; overflow:hidden;'><input id="upfile" type="file" value="upload" onchange="sub(this)" /></div>
<!-- here you can have file submit button or you can write a simple script to upload the file automatically-->
<!-- <input type="submit" value='submit' > -->
</form>

All rendering engines automatically generate a button when an <input type="file"> is created. Historically, that button has been completely un-styleable. However, Trident and WebKit have added hooks through pseudo-elements.
Trident
As of IE10, the file input button can be styled using the ::-ms-browse pseudo-element. Basically, any CSS rules that you apply to a regular button can be applied to the pseudo-element. For example:
::-ms-browse {
background: black;
color: red;
padding: 1em;
}
<input type="file">
This displays as follows in IE10 on Windows 8:
WebKit
WebKit provides a hook for its file input button with the ::-webkit-file-upload-button pseudo-element. Again, pretty much any CSS rule can be applied, therefore the Trident example will work here as well:
::-webkit-file-upload-button {
background: black;
color: red;
padding: 1em;
}
<input type="file">
This displays as follows in Chrome 26 on OS X:

Hide it with css and use a custom button with $(selector).click() to activate the the browse button. then set an interval to check the value of the file input type. the interval can display the value for the user so the user can see whats getting uploaded. the interval will clear when the form is submitted [EDIT] Sorry i have been very busy was meaning to update this post, here is an example
<form action="uploadScript.php" method="post" enctype="multipart/form-data">
<div>
<!-- filename to display to the user -->
<p id="file-name" class="margin-10 bold-10"></p>
<!-- Hide this from the users view with css display:none; -->
<input class="display-none" id="file-type" type="file" size="4" name="file"/>
<!-- Style this button with type image or css whatever you wish -->
<input id="browse-click" type="button" class="button" value="Browse for files"/>
<!-- submit button -->
<input type="submit" class="button" value="Change"/>
</div>
$(window).load(function () {
var intervalFunc = function () {
$('#file-name').html($('#file-type').val());
};
$('#browse-click').on('click', function () { // use .live() for older versions of jQuery
$('#file-type').click();
setInterval(intervalFunc, 1);
return false;
});
});

::file-selector-button
https://developer.mozilla.org/en-US/docs/Web/CSS/::file-selector-button
This is a new selector that can be used to style the file selector button.
It has full support on recent browser versions.
input[type=file]::file-selector-button {
border: 2px solid #6c5ce7;
padding: .2em .4em;
border-radius: .2em;
background-color: #a29bfe;
transition: 1s;
}
input[type=file]::file-selector-button:hover {
background-color: #81ecec;
border: 2px solid #00cec9;
}
<form>
<label for="fileUpload">Upload file</label>
<input type="file" id="fileUpload">
</form>
Here is another snippet that demonstrates different styling:
.input_container {
border: 1px solid #e5e5e5;
}
input[type=file]::file-selector-button {
background-color: #fff;
color: #000;
border: 0px;
border-right: 1px solid #e5e5e5;
padding: 10px 15px;
margin-right: 20px;
transition: .5s;
}
input[type=file]::file-selector-button:hover {
background-color: #eee;
border: 0px;
border-right: 1px solid #e5e5e5;
}
<form>
<div class="input_container">
<input type="file" id="fileUpload">
</div>
</form>
I felt that this answer was needed as most answers here are outdated.

$('.new_Btn').click(function() {
$('#html_btn').click();
});
.new_Btn {
// your css propterties
}
#html_btn {
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="new_Btn">SelectPicture</div><br>
<input id="html_btn" type='file' /><br>
You can reach your goals too without jQuery with normal JavaScript.
Now the newBtn is linkes with the html_btn and you can style your new btn like you want :D

If you are using Bootstrap 3, this worked for me:
See https://www.abeautifulsite.net/posts/whipping-file-inputs-into-shape-with-bootstrap-3/
.btn-file {
position: relative;
overflow: hidden;
}
.btn-file input[type=file] {
position: absolute;
top: 0;
right: 0;
min-width: 100%;
min-height: 100%;
font-size: 100px;
text-align: right;
filter: alpha(opacity=0);
opacity: 0;
outline: none;
background: white;
cursor: inherit;
display: block;
}
<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<span class="btn btn-primary btn-file">
Browse...<input type="file">
</span>
Which produces the following file input button:

Working example here with native Drag and drop support : https://jsfiddle.net/j40xvkb3/
When styling a file input, you shouldn't break any of native interaction
the input provides.
The display: none approach breaks the native drag and drop support.
To not break anything, you should use the opacity: 0 approach for the input, and position it using relative / absolute pattern in a wrapper.
Using this technique, you can easily style a click / drop zone for the user, and add custom class in javascript on dragenter event to update styles and give user a feedback to let him see that he can drop a file.
HTML :
<label for="test">
<div>Click or drop something here</div>
<input type="file" id="test">
</label>
CSS :
input[type="file"] {
position: absolute;
left: 0;
opacity: 0;
top: 0;
bottom: 0;
width: 100%;
}
div {
position: absolute;
left: 0;
top: 0;
bottom: 0;
width: 100%;
display: flex;
align-items: center;
justify-content: center;
background: #ccc;
border: 3px dotted #bebebe;
border-radius: 10px;
}
label {
display: inline-block;
position: relative;
height: 100px;
width: 400px;
}
Here is a working example (with additional JS to handle dragover event and dropped files).

Hope this helped !

I am able to do it with pure CSS using below code. I have used bootstrap and font-awesome.
<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.css" rel="stylesheet" />
<label class="btn btn-default btn-sm center-block btn-file">
<i class="fa fa-upload fa-2x" aria-hidden="true"></i>
<input type="file" style="display: none;">
</label>

ONLY CSS
Use this very simple and EASY
.choose::-webkit-file-upload-button {
color: white;
display: inline-block;
background: #1CB6E0;
border: none;
padding: 7px 15px;
font-weight: 700;
border-radius: 3px;
white-space: nowrap;
cursor: pointer;
font-size: 10pt;
}
<label>Attach your screenshort</label>
<input type="file" multiple class="choose">

<label>
<input type="file" />
</label>
You can wrap your input type="file" inside of a label for the input. Style the label however you'd like and hide the input with display: none;

This approach gives you the whole flexibility! ES6 / VanillaJS!
html:
<input type="file" style="display:none;"></input>
<button>Upload file</button>
javascript:
document.querySelector('button').addEventListener('click', () => {
document.querySelector('input[type="file"]').click();
});
This hides the input-file button, but under the hood clicks it from another normal button, that you can obviously style like any other button. This is the only solution with no downside apart from a useless DOM-node. Thanks to display:none;, the input-button does not reserve any visible space in the DOM.
(I don't know anymore to whom to give props for this. But I got that idea from somewhere here on Stackoverflow.)

Put upload file button over your nice button or element and hide it.
Very simple and will work on any browser
<div class="upload-wrap">
<button type="button" class="nice-button">upload_file</button>
<input type="file" name="file" class="upload-btn">
</div>
Styles
.upload-wrap {
position: relative;
}
.upload-btn {
position: absolute;
left: 0;
opacity: 0;
}

Here is a solution which doesn't really style the <input type="file" /> element but instead uses a <input type="file" /> element on top of other elements (which can be styled). The <input type="file" /> element is not really visible hence, the overall illusion is of a nicely styled file upload control.
I came across this problem recently and despite the plethora of answers on Stack Overflow, none really seemed to fit the bill. In the end, I ended up customizing this so as to have a simple and an elegant solution.
I have also tested this on Firefox, IE (11, 10 & 9), Chrome and Opera, iPad and a few android devices.
Here's the JSFiddle link -> http://jsfiddle.net/umhva747/
$('input[type=file]').change(function(e) {
$in = $(this);
$in.next().html($in.val());
});
$('.uploadButton').click(function() {
var fileName = $("#fileUpload").val();
if (fileName) {
alert(fileName + " can be uploaded.");
}
else {
alert("Please select a file to upload");
}
});
body {
background-color:Black;
}
div.upload {
background-color:#fff;
border: 1px solid #ddd;
border-radius:5px;
display:inline-block;
height: 30px;
padding:3px 40px 3px 3px;
position:relative;
width: auto;
}
div.upload:hover {
opacity:0.95;
}
div.upload input[type="file"] {
display: input-block;
width: 100%;
height: 30px;
opacity: 0;
cursor:pointer;
position:absolute;

}
.uploadButton {
background-color: #425F9C;

}
.fileName {
font-family: Arial;

<span class="fileName">Select file..</span>
</div>
<input type="button" class="uploadButton" value="Upload File" />
</form>
Hope this helps!!!

This is simple with jquery. To give a code example of Ryan's suggestion with a slight modification.
Basic html:
<div id="image_icon"></div>
<div id="filename"></div>
<input id="the_real_file_input" name="foobar" type="file">
Be sure to set the styling on the input when you're ready: opacity: 0
You can't set display: none because it needs to be clickable. But you can position it under the "new" button or tuck in under something else with z-index if you prefer.
Setup some jquery to click the real input when you click the image.
$('#image_icon').click(function() {
$('#the_real_file_input').click();
});
Now your button is working. Just cut and paste the value when changed.
$('input[type=file]').bind('change', function() {
var str = "";
str = $(this).val();
$("#filename").text(str);
}).change();
Tah dah! You may need to parse the val() to something more meaningful but you should be all set.

Here is a PURE CSS, Javascript-free, Bootstrap-free, 100% cross-browser solution! Just cut-and-paste one block of styles, then test your file upload control.
This solution does NOT attempt to hide then recreate the original HTML element like the other posts here do. It uses plain CSS without any circus tricks or third party tools to style the original file upload form control for all the major browsers. You do not need to even change your HTML code! Just cut-and-paste the code below into your web page to test it...
<style>
/* Note: This CSS will style all instances of
<input type=file /> controls in your website. */
input[type="file"],
input[type="file"]:visited,
input[type="file"]:hover,
input[type="file"]:focus,
input[type="file"]:active {
margin:0;
padding: 0em 0em;/* fallback: older browsers like IE 1-8 need "em" */
padding: 0rem 0rem;/* older browsers dont know what "rem" is */
overflow: hidden; /* long file names overflow so just hide the end */
background: #fff;
border-radius: .2em;
border-radius: .2rem;
outline: none;
border: 2px solid #bbb;
cursor: pointer;
-webkit-appearance: textfield;
-moz-appearance: textfield;
}
input[type="file"]:hover {
background: #f9f9ff; /* Optional rollover color: I am using a light blue to indicate an interaction */
border: 2px solid #999;
}
input[type="file"]:visited,
input[type="file"]:focus,
input[type="file"]:active {
background: #fff; /* Default back to white when focused. */
border: 2px solid #999;
}
/* Note: These "disabled" selectors blow up in IE so have to be separated from the same styles above. */
input[type="file"]:disabled {
margin: 0;
padding: 0em 0em;
padding: 0rem 0rem;
overflow: hidden; /* long file names overflow so just hide the end */
background: #ddd;
border-radius: .2em;
border-radius: .2rem;
outline: none;
border: 2px solid #bbb;
cursor: pointer;
-webkit-appearance: textfield;
-moz-appearance: textfield;
}
input[type="file"]:disabled:hover {
background: #ddd; /* disabled-readonly buttons should be grey */
border: 2px solid #999;
}
input[type="file"]:disabled:visited,
input[type="file"]:disabled:focus,
input[type="file"]:disabled:active {
background: #ddd; /* disabled-readonly buttons should be grey */
border: 2px solid #999;
}
/* IE UPLOAD BUTTON STYLE: This attempts to alter the file upload button style in IE. Keep in mind IE gives you limited design control but at least you can customize its upload button.*/

This is what the file upload control looks like in Firefox, Chrome, and Edge using the CSS below. This is a very simple clean design. You can change it to look any way you like:
Internet Explorer gives you limited design control, but at least you can manipulate the control using CSS enough to change a few things, including rounded borders and colors:
The advantages to my solution are:
You stick with simple CSS to style the original HTML input control
You can see one or more file names in the file input textbox
Screen readers and ARIA-friendly devices can interact normally with your file upload control
You can set tabindex on your HTML element so its part of the tab order
Because you are using plain HTML and CSS, your file input button works perfectly in old and new browsers
ZERO JavaScript required!
Runs and loads lighting fast in even the oldest of browsers
Because your are not using "display:none" to hide the control, its file block stream data is never disabled from reaching the server in any old or new browser version known
You do not need goofy JavaScript tricks, Bootstrap, or to try and hide/recreate your file input control. That just destroys usability for everyone online. Styling the original HTML control means your file upload control is guaranteed to work well in 25 years worth of web browsers, old and new.
This is why you cannot trust all these scripted hacks here that erase, rewrite, or destroy HTML just to try and recreate some visual experience. That shows that you do not understand how HTML is used or why its been around for 30 years practically unchanged. You should never try and rewrite HTML's native form control functionality. Why? There is more to using natural HTML in websites than just manipulation of markup for some forced visual experience. The trade-offs of limited visual design in these replaced HTML elements was designed that way for a reason.
My advice: Stay with simple HTML and CSS solutions and you will have ZERO problems as a web developer.

<input type="file" name="media" style="display-none" onchange="document.media.submit()">
I would normally use simple javascript to customize the file input tag.A hidden input field,on click of button,javascript call the hidden field,simple solution with out any css or bunch of jquery.
<button id="file" onclick="$('#file').click()">Upload File</button>

VISIBILITY:hidden TRICK
I usually go for the visibility:hidden trick
this is my styled button
<div id="uploadbutton" class="btn btn-success btn-block">Upload</div>
this is the input type=file button. Note the visibility:hidden rule
<input type="file" id="upload" style="visibility:hidden;">
this is the JavaScript bit to glue them together. It works
<script>
$('#uploadbutton').click(function(){
$('input[type=file]').click();
});
</script>

Multiple file solution with converted filename
Bootstrap EXAMPLE
HTML:
<div>
<label class="btn btn-primary search-file-btn">
<input name="file1" type="file" style="display:None;"> <span>Choose file</span>
</label>
<span>No file selected</span>
</div>
<div>
<label class="btn btn-primary search-file-btn">
<input name="file2" type="file" style="display:None;"> <span>Choose file</span>
</label>
<span>No file selected</span>
</div>
1. JS with jQuery:
$().ready(function($){
$('.search-file-btn').children("input").bind('change', function() {
var fileName = '';
fileName = $(this).val().split("\\").slice(-1)[0];
$(this).parent().next("span").html(fileName);
})
});
2. JS without jQuery
Array.prototype.forEach.call(document.getElementsByTagName('input'), function(item) {
item.addEventListener("change", function() {
var fileName = '';
fileName = this.value.split("\\").slice(-1)[0];
this.parentNode.nextElementSibling.innerHTML = fileName;
});
});

the only way i can think of is to find the button with javascript after it gets rendered and assign a style to it
you might also look at this writeup

Here we use a span to trigger input of type file and we simply customized that span, so we can add any styling using this way.
Note that we use input tag with visibility:hidden option and trigger it in the span.
.attachFileSpan{
color:#2b6dad;
cursor:pointer;
}
.attachFileSpan:hover{
text-decoration: underline;
}
<h3> Customized input of type file </h3>
<input id="myInput" type="file" style="visibility:hidden"/>
<span title="attach file" class="attachFileSpan" onclick="document.getElementById('myInput').click()">
Attach file
</span>
Reference

Here is a solution, that also shows the chosen file name:
http://jsfiddle.net/raft9pg0/1/
HTML:
<label for="file-upload" class="custom-file-upload">Chose file</label>
<input id="file-upload" type="file"/>
File: <span id="file-upload-value">-</span>
JS:
$(function() {
$("input:file[id=file-upload]").change(function() {
$("#file-upload-value").html( $(this).val() );
});
});
CSS:
input[type="file"] {
display: none;
}
.custom-file-upload {
background: #ddd;
border: 1px solid #aaa;
border-top: 1px solid #ccc;
border-left: 1px solid #ccc;
-moz-border-radius: 3px;
-webkit-border-radius: 3px;
border-radius: 3px;
color: #444;
display: inline-block;
font-size: 11px;
font-weight: bold;
text-decoration: none;
text-shadow: 0 1px rgba(255, 255, 255, .75);
cursor: pointer;
margin-bottom: 20px;
line-height: normal;
padding: 8px 10px; }

This is a nice way to do it with material / angular file upload.
You could do the same with a bootstrap button.
Note I used <a> instead of <button> this allows the click events to bubble up.
<label>
<input type="file" (change)="setFile($event)" style="display:none" />
<a mat-raised-button color="primary">
<mat-icon>file_upload</mat-icon>
Upload Document
</a>
</label>

Maybe a lot of awnsers. But I like this in pure CSS with fa-buttons:
.divs {
position: relative;
display: inline-block;
background-color: #fcc;
}
.inputs {
position:absolute;
left: 0px;
height: 100%;
width: 100%;
opacity: 0;
background: #00f;
z-index:999;
}
.icons {
position:relative;
}
<div class="divs">
<input type='file' id='image' class="inputs">
<i class="fa fa-image fa-2x icons"></i>

Don't be fooled by "great" CSS-only solutions that are actually very browser-specific, or that overlay the styled button on top of the real button, or that force you to use a <label> instead of a <button>, or any other such hack. JavaScript IS necessary to get it working for general usage. Please study how gmail and DropZone do it if you don't believe me.
Just style a normal button however you want, then call a simple JS function to create and link a hidden input element to your styled button.
<!DOCTYPE html>
<meta charset="utf-8">
<style>
button {
width : 160px;
height : 30px;
font-size : 13px;
border : none;
text-align : center;
background-color : #444;
color : #6f0;
}
button:active {
background-color : #779;
}
</style>
<button id="upload">Styled upload button!</button>
<script>
function Upload_On_Click(id, handler) {
var hidden_input = null;
document.getElementById(id).onclick = function() {hidden_input.click();}
function setup_hidden_input() {
hidden_input && hidden_input.parentNode.removeChild(hidden_input);
hidden_input = document.createElement("input");
hidden_input.setAttribute("type", "file");
hidden_input.style.visibility = "hidden";
document.querySelector("body").appendChild(hidden_input);
hidden_input.onchange = function() {
handler(hidden_input.files[0]);
setup_hidden_input();
};
}
setup_hidden_input();
}
Upload_On_Click("upload", function(file) {
console.log("GOT FILE: " + file.name);
});
</script>
Notice how the above code re-links it after every time the user chooses a file. This is important because "onchange" is only called if the user changes the filename. But you probably want to get the file every time the user provides it.

Update Nevermind, this doesn't work in IE or it's new brother, FF. Works on every other type of element as expected, but doesn't work on file inputs. A much better way to do this is to just create a file input and a label that links to it. Make the file input display none and boom, it works in IE9+ seamlessly.
Warning: Everything below this is crap!
By using pseudo elements positioned/sized against their container, we can get by with only one input file (no additional markup needed), and style as per usual.
Demo
<input type="file" class="foo">
<style>
.foo {
display: block;
position: relative;
width: 300px;
margin: auto;
cursor: pointer;
border: 0;
height: 60px;
border-radius: 5px;
outline: 0;
}
.foo:hover:after {
background: #5978f8;
}
.foo:after {
transition: 200ms all ease;
border-bottom: 3px solid rgba(0,0,0,.2);
background: #3c5ff4;
text-shadow: 0 2px 0 rgba(0,0,0,.2);
color: #fff;
font-size: 20px;
text-align: center;
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
display: block;
content: 'Upload Something';
line-height: 60px;
border-radius: 5px;
}
</style>
Enjoy guys!
Old Update
Turned this into a Stylus mixin. Should be easy enough for one of you cool SCSS cats to convert it.
file-button(button_width = 150px)
display block
position relative
margin auto
cursor pointer
border 0
height 0
width 0
outline none
&:after
position absolute
top 0
text-align center
display block
width button_width
left -(button_width / 2)
Usage:
<input type="file">
input[type="file"]
file-button(200px)

I've found a very easy method to switch the file button to a picture.
You just label a picture and place it on top of the file button.
<html>
<div id="File button">
<div style="position:absolute;">
<!--This is your labeled image-->
<label for="fileButton"><img src="ImageURL"></label>
</div>
<div>
<input type="file" id="fileButton"/>
</div>
</div>
</html>
When clicking on the labeled image, you select the file button.

This week I also needed to custom the button and display the selected file name aside it, so after reading some of the answers above (Thanks BTW) I came up with the following implementation:
HTML:
<div class="browse">
<label id="uploadBtn" class="custom-file-upload">Choose file
<input type="file" name="fileInput" id="fileInput" accept=".yaml" ngf-select ngf-change="onFileSelect($files)" />
</label>
<span>{{fileName}}</span>
</div>
CSS
input[type='file'] {
color: #a1bbd5;
display: none;
}
.custom-file-upload {
border: 1px solid #a1bbd5;
display: inline-block;
padding: 2px 8px;
cursor: pointer;
}
label{
color: #a1bbd5;
border-radius: 3px;
}
Javascript (Angular)
app.controller('MainCtrl', function($scope) {
$scope.fileName = 'No file chosen';
$scope.onFileSelect = function ($files) {
$scope.selectedFile = $files;
$scope.fileName = $files[0].name;
};
});
Basically I'm working with ng-file-upload lib, Angular-wise I'm binding the filename to my $scope and giving it the initial value of 'No file chosen', I'm also binding the onFileSelect() function to my scope so when a file gets selected I'm getting the filename using ng-upload API and assign it to the $scope.filename.

Simply simulate a click on the <input> by using the trigger() function when clicking on a styled <div>. I created my own button out of a <div> and then triggered a click on the input when clicking my <div>. This allows you to create your button however you want because it's a <div> and simulates a click on your file <input>. Then use display: none on your <input>.
// div styled as my load file button
<div id="simClick">Load from backup</div>
<input type="file" id="readFile" />
// Click function for input
$("#readFile").click(function() {
readFile();
});
// Simulate click on the input when clicking div
$("#simClick").click(function() {
$("#readFile").trigger("click");
});

Decode this Example of Dynamically Increasing Input Width

I've been doing a huge amount of reading here and on other websites about how to dynamically increase an input field's width based on its content. All the solutions so far have only worked in part, but I have found a website where it works perfectly:
https://paper.fiftythree.com/search
They've even given some vague instruction as to how they did it:
http://making.fiftythree.com/fluid-text-inputs/
But I can't for the life of me work out how to implement this on my own website.
This is my form structure at the moment:
<form action="/" class="search-form">
<input type="text" name="s" class="_input" placeholder="What are you looking for?">
<button type="submit" class="_button">Search</button>
</form>
My reason for trying to do this is that the form as a whole has a border underneath it. I would then like text that is typed in to have its own border-bottom 'grow' with the text in a different colour. The input field being a smaller width with its own border works, but I am stuck on a smooth dynamic experience for its width.
Could anyone help? Thanks.

On this example we can do this:
Input positioned absolute with fixed width this never changes, and will get the data
An element that will change the width based on the value from the input and the text transparent so that way we only see the input text.
Centered elements creating the ilusion of increase of the width
$('input').on('keypress', function() {
$('span').text($(this).val())
})
.container {
text-align: center;
position: relative;
font-size:25px;
}
.container img, .container span {
display: inline-block;
line-height: 50px;
margin-right: -4px;
vertical-align: middle;
}
.container span {
padding: 0 10px;
font-family: sans-serif;
color: transparent;
overflow: hidden;
white-space: nowrap;
max-width: 250px;
}
.container input {
width: 250px;
border: none;
text-align: center;
font-size:inherit;
padding: 0 50px;
position: absolute;
left: 50%;
top: 50%;
z-index: 5;
background: transparent;
transform: translate(-50%, -50%)
}
input:focus {
outline: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<img src="http://placekitten.com/50" alt="">
<span>Type here</span>
<input type="text" placeholder="Type here">
<img src="http://placekitten.com/50" alt="">
</div>
Note: Still have some issues when deleting text, but you get the idea

overflow:hidden is not correctly hiding absolutely positioned elements

I'm creating a dropdown settings box, and inside it I want to be able to have dropdown submenus to group settings. The submenus should slide down, and to do so, I am using jQuery to slide down the div that contains them. However, the absolutely positioned toggles that I have appear immediately, despite the fact that they are outside the div, which is set to overflow: hidden, as can be seen in this image:
This is a sample from my html:
<div id="settings-content" class="hover-content">
<div class="setting-expandable">
Panels to display<span class="expand-button pointer">+</span>
<div class="hide expand-content">
<label class="pointer">YouTube - LinusTechTips
<input type="checkbox" class="display-none setting" data-setting="panel.yt.ltt"><span class="toggle"></span>
</label>
<br/>
<label class="pointer">YouTube - TechQuickie
<input type="checkbox" class="display-none setting" data-setting="panel.yt.tq"><span class="toggle"></span>
</label>
<br/>
<label class="pointer">YouTube - Channel Superfun
<input type="checkbox" class="display-none setting" data-setting="panel.yt.csf"><span class="toggle"></span>
</label>
<br/>
</div>
</div>
</div>
and my CSS:
.toggle {
height: 13px;
margin: 3px 0;
position: absolute;
right: 10px;
width: 27px;
}
.toggle::after {
background - color: red;
content: "";
height: 13px;
position: absolute;
right: 0;
width: 13px;
transition: 0.2s linear all;
}
.expand-content {
margin-left: 10px;
margin-top:3px;
overflow:hidden
}
.hover-content {
position: absolute;
width: 500px;
right: 15px;
background-color: inherit;
top: -15px;
border: 2px black solid;
border-radius: 14px;
padding: 5px;
display: block;
}
JS is essentially $("...").click(function(){ $("...").slideUp(); });
If I deliberately position them outside of the content area, and set overflow hidden on each thing in turn, it only hides when it affects the #settings-content container div.
I have made a fiddle for it here: http://jsfiddle.net/S4DSh/1/
I would greatly appreciate some guidance as to how I should fix this because it looks pretty weird at the moment.
Thanks in advance!

Set it's container to position:relative and overflow:hidden.
.setting-expandable {
position:relative;
overflow:hidden;
}
DEMO
You could also just add position:relative; to .expand-content but that looks like it moves the toggles a little bit.
Also see this answer it's basically the same question.

What you want to do is change the z-index for your divs.
You should put a lower z-index value on things you want to stay in the back and higher z-index values to what you want in the front. And correct me if I'm wrong but, a value of -1 would be behind the body. You can put any value like 999
#DivInTheBack{
z-index:12;
}
#DivInTheFront{
z-index:13;
}
You should take a look at the w3schools reference: http://www.w3schools.com/cssref/pr_pos_z-index.asp

Menu, under search bar on nav-bar in Bootstrap...not compatible

I am trying to create a search bar with results that appear right under the bar, but I am faced with a number of problems while trying to implement this. I am new in web programming, which is why I prefer to use bootstrap because of its compatibility on different screen sizes. In this case, I don't know which method to use and I simply created "div" under the bar, but I am not sure if it is the correct way. Would be happy if you gave me suggestion.
Below I included the code with css that I used.
I gave hard-coded value for the width as 174px, while I need something that automatically
identifies the width of search bar and sets that value as maximum.
ID="searchResults" is the string that I get in real time using jQuery and Ajax.
Would be happy if you give me advice about the way how to implement this.
<div class="navbar-form navbar-left">
<input class="form-control" placeholder="Search..." type="text"
autocomplete = off id = "autocomplete_search">
<div id="searchResults"
style="position: absolute;
width: 174px;
background: white;
border-bottom-left-radius: 10px;
border-bottom-right-radius: 10px;
max-height: 200px;
overflow-y: auto;
margin-top: -3px;"> </div>
</div>

your attemp is ok. .navbar-form navbar-left needs to be position: relative;.
If you do that, you can use this element to position and size the absolute container of #searchResults.
Your HTML is not valid, here is a more clean version:
<div class="navbar-form navbar-left">
<input class="form-control" placeholder="Search..." type="text" autocomplete="off" id="autocomplete_search" />
<div id="searchResults">So much results...</div>
</div>
Here is some CSS to put the html in shape:
.navbar-form
{
position: relative;
/* just a little demo */
margin-left:200px;
}
.form-control
{
width: 100%;
}
#searchResults
{
position: absolute;
width: auto;
background: white;
border-bottom-left-radius: 10px;
border-bottom-right-radius: 10px;
max-height: 200px;
overflow-y: auto;
border: 1px solid gray;
/*This is relative to the navbar now*/
left: 0;
right: 0;
top: 20px;
}
And here is a little demo: http://jsfiddle.net/NicoO/ZAyN9/

adding search icon to input box

<div id="inputs">
<input type="text" value="">
<input type="text" value="">
</div>
<input type="button" id="add" value="Add input">
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<script type="text/javascript">
$(function(){
$('#add').click(function(){
$('#inputs').append('<input type="text" value="">');
});
});
</script>
Within the code above, i want to add a search icon for every new input generated with a button (id=add ; not shown here for simplicity). This would be a typical input:
<label>
<input type="text" class="search" name="word" autofocus="autofocus" />
<span class="search-icon">
<span class="glass"></span>
<span class="handle"></span>
</span>
</label>
With CSS i could position the search icons in a fixed way.
Thanks

Here's the CSS code that I'd use:
#add {
padding: 17px;
padding-left: 55px;
width: 300px;
border: 1px solid #f5f5f5;
font-size: 13px;
color: gray;
background-image: url('http://i47.tinypic.com/r02vbq.png');
background-repeat: no-repeat;
background-position: left center;
outline: 0;
}
Note: I added a lot of extra codes to make the search box look better, the necessary code to make the search box apear is padding-left, background-image:url, background-repeat and background-position. Replace "http://i47.tinypic.com/r02vbq.png" with whatever search icon you want.
It's also important to know that now in HTML5, most browsers render
<input type="search" results>
with a search icon. The input type search makes it a search box, with a "x" button to clear, and adding "results" also displays a search box. Of course you could also add an x button with CSS and JavaScript to a regular search box. It's also important to note that input type search allows very little styling. Demo on Safari on a Mac:
Tell me if this helps you, and make sure to mark as the answer. :)

Put the image into the span, for example using background-image, then give it a relative position and move it to the left so it overlaps the right end of the search box, for example:
#g-search-button {
display: inline-block;
width: 16px;
height: 16px;
position: relative;
left: -22px;
top: 3px;
background-color: black; /* Replace with your own image */
}
