Style input range background before thumb - javascript

I want to style the bar before the thumb with a different color on a range input. I'v tried looking for a solution but I havent found a proper solution. This is what I need it to look like:
Chrome doesnt seem to support input[type='range']::-webkit-slider-thumb:before anymore and I am at a loss how to style it. Here's what I have so far:
input[type='range'] {
min-width: 100px;
max-width: 200px;
&::-webkit-slider-thumb {
-webkit-appearance: none !important;
background-color: #white;
border: 1px solid #gray-4;
height: 14px;
width: 14px;
&:hover,
&:focus,
&:active {
border-color: #blue;
background-color: #gray-2;
}
}
&::-webkit-slider-runnable-track {
background-color: #gray-2;
border: 1px solid #gray-4;
}
}


document.querySelectorAll(".__range").forEach(function(el) {
el.oninput =function(){
var valPercent = (el.valueAsNumber - parseInt(el.min)) /
(parseInt(el.max) - parseInt(el.min));
var style = 'background-image: -webkit-gradient(linear, 0% 0%, 100% 0%, color-stop('+ valPercent+', #29907f), color-stop('+ valPercent+', #f5f6f8));';
el.style = style;
};
el.oninput();
});
.__range{
margin:30px 0 20px 0;
-webkit-appearance: none;
background-color: #f5f6f8;
height: 3px;
width: 100%;
margin: 10px auto;
}
.__range:focus{
outline:none;
}
.__range::-webkit-slider-thumb{
-webkit-appearance: none;
width: 20px;
height: 20px;
background: #29907f;
border-radius: 50%;
cursor: -moz-grab;
cursor: -webkit-grab;
}
<input class="__range" id="rng" name="rng" value="30" type="range" max="100" min="1" value="100" step="1">


The trick in the post referenced by shambalambala is clever, but I don't think it will work in this case if you want to get something that looks exactly like the image you show. The approach there is to put a shadow on the thumb to create the different coloring to the left of the thumb. Since the shadow extends in the vertical, as well as the horizontal, direction, you also have to add overflow:hidden to the range or the track in order to clip the shadow. Unfortunately, this also clips the thumb. So if you want a thumb that extends beyond the track in the vertical dimension, such as in the image you show where the thumb is a circle with a diameter larger than the track width, this won't work.
I'm not sure there's a pure CSS solution to this problem. With JavaScript, one way around this is to make two range elements that overlap exactly. For one range element, you will see only the thumb and for one you will see only the track. You can use the shadow approach on the track element to get the different color before the thumb. You can style the thumb on the thumb range however you want, and since overflow is not set to hidden for this range element, it can extend beyond the width of the track. You can then use JavaScript to yoke the two range elements together, so that when you move the thumb on the thumb-visible element, the value of the track-visible element also changes.
For example (works in webkit browsers--will need some additional styling for other browsers):
<html>
<head>
<style>
.styled_range {
position: relative;
padding: 10px;
}
input[type=range] {
-webkit-appearance: none;
width: 600px;
background: transparent;
position: absolute;
top: 0;
left: 0;
}
input[type=range]::-webkit-slider-thumb {
-webkit-appearance: none;
}
input[type=range]:focus {
outline: none;
}
input[type=range]::-webkit-slider-runnable-track {
width: 100%;
height: 12px;
}
.track_range {
pointer-events: none;
}
.track_range::-webkit-slider-runnable-track {
background: #D0D0D0;
border-radius: 6px;
overflow: hidden;
}
.track_range::-webkit-slider-thumb {
-webkit-appearance: none;
background: transparent;
height: 1px;
width: 1px;
box-shadow: -600px 0 0 600px #666666;
}
.thumb_range::-webkit-slider-runnable-track {
background: transparent;
cursor: pointer;
}
.thumb_range::-webkit-slider-thumb {
-webkit-appearance: none;
border: 3px solid #ffffff;
border-radius: 20px;
height: 40px;
width: 40px;
background: #1180AD;
cursor: pointer;
margin: -12px 0px 0px 0px;
}
</style>
</head>

</div>
<br/>

</form>
</body>
<script>
window.onload = function() {
var styledRanges = document.getElementsByClassName('styled_range');
for (var i=0; i<styledRanges.length; i++) {
var thumbRange = null, trackRange = null;
for (var j=0; j<styledRanges[i].children.length; j++) {
var child = styledRanges[i].children[j];
if (child.className === 'thumb_range')

How to set textarea height using min-height?

I am trying to create a message input field, using textarea. The reason I am using textarea is to be able to dynamically change the height.
To be able to dynamically change the height of the textarea and the parent divs, I have implemented this code.
The code works, just fine. To be able to use this JavaScript code I have to use min-height on the textarea. The problem is that I want to set the height of the textarea to 10px but it simply doesn't want to work, when using min-height. I does somehow work when I use height, but then the JavaScript won't work.
UPDATE:
I am just trying to create a field where the user can write a message and then post it.
Currently the textarea is too tall in my opinion, there is no reason for it to be taller than needed. So i want the height to initially be 20px, and then be able to expand as the user types.
UPDATE UPDATE:
I want to know how to set the height of the textarea to 10px or 20px, but still be able to dynamically change the height when the user types, using the javascript code i have provided
Any ideas on how to solve this? Btw, I'm not very well versed in CSS.
var areaName = "finder__input";
var textarea = document.getElementById(areaName);
textarea.addEventListener("input", function() {
const textarea = document.querySelector("textarea");
const textareaHeight = textarea.clientHeight;

textarea.style.height = textarea.scrollHeight + "px";

Resize textarea height on input
This is basically similar to this jQuery related question: Resize Textarea on Input.
Here's a rewrite in vanilla JavaScript
const textareaResize = (elTextarea) => {
elTextarea.style.height = "auto";
const h = elTextarea.scrollHeight;
elTextarea.style.height = `${h}px`;
};
document.querySelectorAll(".flexheight").forEach((elTextarea) => {
elTextarea.addEventListener("input", textareaResize); // on input
textareaResize(elTextarea); // on init
});
textarea.flexheight {
resize: none;
width: 100%;
box-sizing: border-box;
font: inherit;
height: 1rem;
}
Starts small and increment height as user types: <br>
<textarea class="flexheight" placeholder="Write a message..."></textarea>
<br>
<textarea class="flexheight" placeholder="Write about yourself..."></textarea>

var areaName = "finder__input";
var textarea = document.getElementById(areaName);
textarea.addEventListener("input", function() {
const textarea = document.querySelector("textarea");
const textareaHeight = textarea.clientHeight;
//textarea.style.height = "10px";
textarea.style.minHeight = textarea.scrollHeight + "px";
});
try using minHeight

Accessible input elements without label [duplicate]

Is it possible to make a HTML5 slider with two input values, for example to select a price range? If so, how can it be done?

I've been looking for a lightweight, dependency free dual slider for some time (it seemed crazy to import jQuery just for this) and there don't seem to be many out there. I ended up modifying #Wildhoney's code a bit and really like it.
function getVals(){
// Get slider values
var parent = this.parentNode;
var slides = parent.getElementsByTagName("input");
var slide1 = parseFloat( slides[0].value );
var slide2 = parseFloat( slides[1].value );
// Neither slider will clip the other, so make sure we determine which is larger
if( slide1 > slide2 ){ var tmp = slide2; slide2 = slide1; slide1 = tmp; }
var displayElement = parent.getElementsByClassName("rangeValues")[0];
displayElement.innerHTML = slide1 + " - " + slide2;
}
window.onload = function(){
// Initialize Sliders
var sliderSections = document.getElementsByClassName("range-slider");
for( var x = 0; x < sliderSections.length; x++ ){
var sliders = sliderSections[x].getElementsByTagName("input");
for( var y = 0; y < sliders.length; y++ ){
if( sliders[y].type ==="range" ){
sliders[y].oninput = getVals;
// Manually trigger event first time to display values
sliders[y].oninput();
}
}
}
}
section.range-slider {
position: relative;
width: 200px;
height: 35px;
text-align: center;
}
section.range-slider input {
pointer-events: none;

overflow: hidden;

top: 15px;
width: 200px;

}

}
section.range-slider input::-moz-range-thumb {

}
section.range-slider input::-moz-range-track {

}
section.range-slider input:last-of-type::-moz-range-track {
-moz-appearance: none;
background: none transparent;
border: 0;
}
section.range-slider input[type=range]::-moz-focus-outer {

No, the HTML5 range input only accepts one input. I would recommend you to use something like the jQuery UI range slider for that task.

Coming late, but noUiSlider avoids having a jQuery-ui dependency, which the accepted answer does not. Its only "caveat" is IE support is for IE9 and newer, if legacy IE is a deal breaker for you.
It's also free, open source and can be used in commercial projects without restrictions.
Installation: Download noUiSlider, extract the CSS and JS file somewhere in your site file system, and then link to the CSS from head and to JS from body:
<!-- In <head> -->
<link href="nouislider.min.css" rel="stylesheet">
<!-- In <body> -->
<script src="nouislider.min.js"></script>
Example usage: Creates a slider which goes from 0 to 100, and starts set to 20-80.
HTML:
<div id="slider">
</div>
JS:
var slider = document.getElementById('slider');
noUiSlider.create(slider, {
start: [20, 80],
connect: true,
range: {
'min': 0,
'max': 100
}
});

Sure you can simply use two sliders overlaying each other and add a bit of javascript (actually not more than 5 lines) that the selectors are not exceeding the min/max values (like in #Garys) solution.
Attached you'll find a short snippet adapted from a current project including some CSS3 styling to show what you can do (webkit only). I also added some labels to display the selected values.
It uses JQuery but a vanillajs version is no magic though.
#Update: The code below was just a proof of concept. Due to many requests I've added a possible solution for Mozilla Firefox (without changing the original code). You may want to refractor the code below before using it.
(function() {
function addSeparator(nStr) {
nStr += '';
var x = nStr.split('.');
var x1 = x[0];
var x2 = x.length > 1 ? '.' + x[1] : '';
var rgx = /(\d+)(\d{3})/;
while (rgx.test(x1)) {
x1 = x1.replace(rgx, '$1' + '.' + '$2');
}
return x1 + x2;
}

Actually I used my script in html directly. But in javascript when you add oninput event listener for this event it gives the data automatically.You just need to assign the value as per your requirement.

The question was: "Is it possible to make a HTML5 slider with two input values, for example to select a price range? If so, how can it be done?"
In 2020 it is possible to create a fully accessible, native, non-jquery HTML5 slider with two thumbs for price ranges. If found this posted after I already created this solution and I thought that it would be nice to share my implementation here.
This implementation has been tested on mobile Chrome and Firefox (Android) and Chrome and Firefox (Linux). I am not sure about other platforms, but it should be quite good. I would love to get your feedback and improve this solution.
This solution allows multiple instances on one page and it consists of just two inputs (each) with descriptive labels for screen readers. You can set the thumb size in the amount of grid labels. Also, you can use touch, keyboard and mouse to interact with the slider. The value is updated during adjustment, due to the 'on input' event listener.
My first approach was to overlay the sliders and clip them. However, that resulted in complex code with a lot of browser dependencies. Then I recreated the solution with two sliders that were 'inline'. This is the solution you will find below.
var thumbsize = 14;
function draw(slider,splitvalue) {
/* set function vars */
var min = slider.querySelector('.min');
var max = slider.querySelector('.max');
var lower = slider.querySelector('.lower');
var upper = slider.querySelector('.upper');
var legend = slider.querySelector('.legend');
var thumbsize = parseInt(slider.getAttribute('data-thumbsize'));
var rangewidth = parseInt(slider.getAttribute('data-rangewidth'));
var rangemin = parseInt(slider.getAttribute('data-rangemin'));
var rangemax = parseInt(slider.getAttribute('data-rangemax'));
/* set min and max attributes */
min.setAttribute('max',splitvalue);
max.setAttribute('min',splitvalue);
/* set css */
min.style.width = parseInt(thumbsize + ((splitvalue - rangemin)/(rangemax - rangemin))*(rangewidth - (2*thumbsize)))+'px';
max.style.width = parseInt(thumbsize + ((rangemax - splitvalue)/(rangemax - rangemin))*(rangewidth - (2*thumbsize)))+'px';
min.style.left = '0px';
max.style.left = parseInt(min.style.width)+'px';
min.style.top = lower.offsetHeight+'px';
max.style.top = lower.offsetHeight+'px';
legend.style.marginTop = min.offsetHeight+'px';
slider.style.height = (lower.offsetHeight + min.offsetHeight + legend.offsetHeight)+'px';
/* correct for 1 off at the end */
if(max.value>(rangemax - 1)) max.setAttribute('data-value',rangemax);
/* write value and labels */
max.value = max.getAttribute('data-value');
min.value = min.getAttribute('data-value');
lower.innerHTML = min.getAttribute('data-value');
upper.innerHTML = max.getAttribute('data-value');
}
function init(slider) {
/* set function vars */
var min = slider.querySelector('.min');
var max = slider.querySelector('.max');
var rangemin = parseInt(min.getAttribute('min'));
var rangemax = parseInt(max.getAttribute('max'));
var avgvalue = (rangemin + rangemax)/2;
var legendnum = slider.getAttribute('data-legendnum');

2022 - Accessible solution - 30 second solution to implement
This solution builds off of this answer by #JoostS. Accessibility is something none of the answers have focused on and that is a problem, so I built off of the above answer by making it more accessible & extensible since it had some flaws.
Usage is very simple:
Use the CDN or host the script locally: https://cdn.jsdelivr.net/gh/maxshuty/accessible-web-components/dist/simpleRange.min.js
Add this element to your template or HTML: <range-selector min-range="0" max-range="1000" />
Hook into it by listening for the range-changed event (or whatever event-name-to-emit-on-change you pass in)
That's it. View the full demo here. You can easily customize it by simply applying attributes like inputs-for-labels to use inputs instead of labels, slider-color to adjust the color, and so much more!
Here is a fiddle:
window.addEventListener('range-changed', (e) => {console.log(`Range changed for: ${e.detail.sliderId}. Min/Max range values are available in this object too`)})
<script src="https://cdn.jsdelivr.net/gh/maxshuty/accessible-web-components#latest/dist/simpleRange.min.js"></script>
<div>
<range-selector
id="rangeSelector1"
min-label="Minimum"
max-label="Maximum"
min-range="1000"
max-range="2022"
number-of-legend-items-to-show="6"
/>
</div>
<div>
<range-selector
id="rangeSelector1"
min-label="Minimum"
max-label="Maximum"
min-range="1"
max-range="500"
number-of-legend-items-to-show="3"
inputs-for-labels
/>
</div>
<div>
<range-selector
id="rangeSelector2"
min-label="Minimum"
max-label="Maximum"
min-range="1000"
max-range="2022"
number-of-legend-items-to-show="3"
slider-color="#6b5b95"
/>
</div>
<div>
<range-selector
id="rangeSelector3"
min-label="Minimum"
max-label="Maximum"
min-range="1000"
max-range="2022"
hide-label
hide-legend
/>
</div>
I decided to address the issues of the linked answer like the labels using display: none (bad for a11y), no visual focus on the slider, etc., and improve the code by cleaning up event listeners and making it much more dynamic and extensible.
I created this tiny library with many options to customize colors, event names, easily hook into it, make the accessible labels i18n capable and much more. Here it is in a fiddle if you want to play around.
You can easily customize the number of legend items it shows, hide or show the labels and legend, and customize the colors of everything, including the focus color like this.
Example using several of the props:
<range-selector
min-label="i18n Minimum Range"
max-label="i18n Maximum Range"
min-range="5"
max-range="555"
number-of-legend-items-to-show="6"
event-name-to-emit-on-change="my-custom-range-changed-event"
slider-color="orange"
circle-color="#f7cac9"
circle-border-color="#083535"
circle-focus-border-color="#3ec400"
/>
Then in your script:
window.addEventListener('my-custom-range-changed-event', (e) => { const data = e.detail; });
Finally if you see that this is missing something that you need I made it very easy to customize this library.
Simply copy this file and at the top you can see cssHelpers and constants objects that contain most of the variables you would likely want to further customize.
Since I built this with a Native Web Component I have taken advantage of disconnectedCallback and other hooks to clean up event listeners and set things up.

Apply different color on two parts of input range

I'm trying to create a seek bar for the video and I want to show black color on the seek bar representing the amount of video which has been downloaded. How can I assign an additional color on the seek bar representing the amount of video downloaded?
I think I didn't explain my question properly. I want a color (e.g. silver) which shows the amount of video which has been downloaded for playing. Silver color on the seek bar can be found in the default html5 video and YouTube video player. (Image provided below)
var player = document.querySelector("video"),
seek_bar = document.querySelector("input"),
_console = document.querySelector("div");
player.ontimeupdate = function() {
seek_bar.value = this.currentTime.toString().split(".")[0];
}
player.addEventListener('progress', function() {
try {
_console.innerHTML = "Downloaded Upto: " + this.buffered.end(0).toString().split(".")[0];
} catch(e) {}
});
video {
width: 90%;
height: 75%;
}
input[type="range"] {
width: 90%;
height: 10px;
background: rgb(110, 170, 250);
border: 1px solid rgb(15, 15, 15);
border-radius: 50px;

SILVER (THE OTHER COLOR) ON THE SEEK_BAR:

Here is an example of something similar I did a couple of years ago:
https://jsfiddle.net/remisture/esyvws3d/
$(window).on("load resize", function() {
// Get the current width of the slider
var sliderWidth = $('[type=range]').width();
// Remove previously created style elements
$('.custom-style-element-related-to-range').remove();
// Add our updated styling
$('<style class="custom-style-element-related-to-range">input[type="range"]::-webkit-slider-thumb { box-shadow: -' + sliderWidth + 'px 0 0 ' + sliderWidth + 'px;}<style/>').appendTo('head');
});
.container {
margin: 0 auto;
width: 500px;
}
input[type='range'] {
width: 100%;
}
/*Chrome*/
#media screen and (-webkit-min-device-pixel-ratio:0) {
input[type='range'] {
overflow: hidden;
-webkit-appearance: none;
background-color: #9a905d;
}
input[type='range']::-webkit-slider-runnable-track {
height: 10px;
-webkit-appearance: none;
color: #13bba4;
margin-top: -1px;
}
input[type='range']::-webkit-slider-thumb {
width: 10px;
-webkit-appearance: none;
height: 10px;
cursor: ew-resize;
background: #434343;
color: #43e5f7;
}
}
/** FF*/
input[type="range"]::-moz-range-progress {
background-color: #43e5f7;
}
input[type="range"]::-moz-range-track {
background-color: #9a905d;
}
/* IE*/
input[type="range"]::-ms-fill-lower {
background-color: #43e5f7;
}
input[type="range"]::-ms-fill-upper {
background-color: #9a905d;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="container">
<input type="range">
</div>

For this I would use the HTML progress element.
Here is how you would style it if you wanted the meter showing the amount of video downloaded to have black color.

-webkit-appearance: none /* Important, otherwise your styles won't have effect */
progress::-webkit-progress-value
background: black

Write value of range to thumb slider

I want to write the value of range input to the thumb. I looked to every single question about this I could find on Google and I didn't find a solution.
I also want to when the value is 10001 I want it to show ∞ instead.
I have tried:
$('#km').on('input', function() {

but it doesn't seem to work.
Any help is appreciated.

:before and :after pseudo will not work on Form Action elements like input.
Instead use a span for example.
$('.range').on('input', function() {
var val = parseInt( this.value, 10 );
var v = val >= parseInt(this.max, 10) ? '∞' : val;
$(this).next('span').attr("data-val", v);
}).trigger('input');
.unit::before {
content: attr(data-val);
}
<input type="range" name="" class="range" min=0 max=10001 step=1 value=0>
<span class="unit">km</span>
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Update input range thumb value
If you want the .range-thumb SPAN element to follow-up with your value you could:
Position your SPAN thumb absolute into a relative parent.
Calculate and transform your value into thumb position px.
Given the thumb is always at width 100 here's an example:
var $range = $('.range');
$range.each(function() {
var $thumb = $(this).next('.range-thumb');
var max = parseInt(this.max, 10);
var tw = 100; // Thumb width. See CSS
$(this).on('input input.range', function() {
var w = $(this).width();
var val = parseInt(this.value, 10);
var txt = val >= max ? '∞' : val;
var xPX = val * (w - tw) / max; // Position in PX
// var xPC = xPX * 100 / w; // Position in % (if ever needed)
$thumb.css({left: xPX}).attr("data-val", txt);
});
});
$range.trigger('input.range'); // Calc on load
$(window).on("resize", () => $range.trigger("input.range")); // and on resize
/* QuickReset */

Removing and readding an element pushes another element down, toggling the float in dev tools causes the element to move back to the correct position

I have a container that holds three items.
One is floated left, another is centered and the last is floated right. If I remove the center item and add it back the right most item gets pushed down and I don't know why.
If you select the right item and view it in Chrome dev tools you can toggle the float: right off/on and then it will be positioned correctly.
This happens in Chrome but does not happen in FireFox. (I have not tested in IE)
I have a demo of the issue here: http://codepen.io/anon/pen/rVyRmy?editors=001
var on = true;
var l = $('<div class="left"></div>');
var r = $('<div class="right"></div>');
var clicky = function() {
if (on) {
$('.container').empty();
$('.container').append(l);
$('.container').append($(
'<div class="fill">' +
'<span>text</span>' +
'<span>text</span>' +
'<span>text</span>' +
'<span>text</span>' +
'</div>'
));
$('.container').append(r);
on = false;
} else {
$('.container').empty();
$('.container').append(l);
$('.container').append($('<input type="text" />'));
$('.container').append(r);
on = true;
}
$('.right').on('click', clicky);
};
$('.right').on('click', clicky);
.container {
width: 400px;
height: 20px;
text-align: center;
background-color: lightgray;
}
.left, .right {
display: inline-block;
width: 14px;
}
.left {
position: relative;
float: left;
}
.left:before {
position: absolute;
top: 4px;
left: 4px;
content: "";
width: 0;
height: 0;
border-style: solid;
border-width: 5px 8.7px 5px 0;
border-color: transparent orange transparent transparent;
}
.right {
position: relative;
float: right;
}
.right:before {
position: absolute;
top: 4px;
right: 4px;
content: "";
width: 0;
height: 0;
border-style: solid;
border-width: 5px 0 5px 8.7px;
border-color: transparent transparent transparent orange;
}
span {
width: 93px;
background-color: green;
display: block;
float: left;
}
div span:first-child {
margin-left: 14px;
}
<div class="container">
<div class="left"></div>
<input type="text" />
<div class="right"></div>
</div>
In the above I clear everything and redraw, I have also tried leaving the left and right elements and just removing/adding the center back but I get the same result.

You can fix this by forcing a redraw on the right element. There are a couple of ways to do this, but my preferred way is $(r).hide().show(0);
$(r).offsetHeight has been known to work, though it doesnt work in the codepen you linked to and it doesnt work in safari. For background I added the code as follows:
else {
$('.container').empty();
$('.container').append(l);
$('.container').append($('<input type="text" class="middle" />'));
$('.container').append(r);
$(r).hide().show(0);
on = true;
}
