Modify the css of a pseudo element using JQuery [duplicate] - javascript

This question already has answers here:
Selecting and manipulating CSS pseudo-elements such as ::before and ::after using javascript (or jQuery)
(26 answers)
Closed 6 years ago.
According to some methods i saw, i tried this to manage the position left of a pseudo element :
$("a").click(function() {
var percent = $("input").val(); //Maths returning an value to set
$(".formEvent").addClass("trig");
console.log(percent);
$("[formEventPointer]").css({ /* CALLING THE PSEUDO ELEMENT*/
left: percent + " %"
});
});
.formEvent {
top: 50px;
/* For the example */
padding: 10px;
height: 80px;
background: #272727;
position: relative;
transition: 300ms;
height: 30px;
margin-top: 10px;
margin-bottom: 0;
}
.formEvent.trig:before {
content: attr(formEventPointer); /* TAKE A SPECIAL LOOK RIGHT THERE */
position: absolute;
left: 5%;
top: -15px;
width: 0;
height: 0;
border-left: 10px solid transparent;
border-right: 10px solid transparent;
border-bottom: 15px solid #272727;
}
a {
background-color: #1162A7;
color: white;
border: 1px solid grey;
box-shadow: 5px 5px 5px black;
cursor: pointer;
padding: 3px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form class='formEvent'>
Change the position :
<input type="range" value="5" max="100" min="0" step="14.285">
<a>Update</a>
</form>
Unfortunately, i'm not able to properly manage as i want the position of the :before pseudo element, with the attribut set in the content. What did i forget, or how can i fix this ?
EDIT :
It's different because i try to use what the question said to perform a task, i'm not asking for what i already use to accomplish a part of a task...

I guess you are doing it in a bit of wrong way.
You are trying to get element using attribute, rather you should try to apply CSS on the basis of attribute
In HTML:
<span>foo</span>
In jQuery:
$('span').hover(function(){
$(this).attr('data-content','bar');
});
In CSS:
span:after {
content: attr(data-content) ' any other text you may want';
}

How to DOM manipulate a pseudo element using JavaScript? [duplicate]

I am using Bootstrap in my project and i need small wrapper. I get it from twitters source and it looks like:
section#my-content {
background-color: #FFFFFF;
border: 1px solid #DDDDDD;
border-radius: 4px 4px 4px 4px;
margin: 15px 0;
padding: 39px 19px 14px;
position: relative;
}
section#my-content:after {
background-color: #F5F5F5;
border: 1px solid #DDDDDD;
border-radius: 4px 0 4px 0;
color: #9DA0A4;
content: "Example";
font-size: 12px;
font-weight: bold;
left: -1px;
padding: 3px 7px;
position: absolute;
top: -1px;
}
So is it possible with JS (jQuery) or or somehow different change content property dynamically ?
You cannot modify pseudo-elements with jQuery (unless you want to add <style> tags). You can, however, change your CSS to make this easier:
content: attr(data-text);
The text will be contained within an attribute on the element:
<div data-text="This is the default text">Test</div>
Now, you can change the attribute with jQuery and the text will change:
$('h1').attr('data-text', 'This is some other text');
Demo: http://jsfiddle.net/8qNjv/
if you meant, can you modify the css rules of a given css class using javascript/jQuery, then you cannot do so.
however, you can use jQuery .css to add new CSS rules dynamically.

You can use a lot:
// style editing
.attr()
.css()
// text editing
.html()
.append()
But maybe its better to add what you realy want, post also the html next time. And what you want as result.

CSS focus on child element change a parent element

I want to style a form that has the label and input inside the form field and when I'll write something inside the input (probably with focus), I want the borders to light up with some blue. Now I have something like this:
HTML
<div class="login-form-field">
<label for="email" class="login-form-label">Email:</label>
<input class="login-form-input" autofocus="autofocus" type="email" value="" name="user[email]" id="user_email">
</div>
CSS
.login-form-input{
margin-left: 20px;
width: 90%;
outline: none;
border: none;
-webkit-box-shadow: none;
-moz-box-shadow: none;
box-shadow: 0 0 0px 1000px white inset;
}
.login-form-label {
font-size: 13px;
font-weight: 300;
padding-left: 20px;
}
.login-form-field{
width: 100%;
border-radius: 0px;
height: 6rem;
border: 0.5px solid grey;
box-shadow: 0px 0px 0px;
}
I already tried to select the parent to made some change and other stuff I found on google. The closest I got was to highlight with blue when the mouser was over it with :hover, but i need the color to stay as I'm with the input selected.
.login-form-field:hover {
border-color: blue !important;
}
Here is the JSFiddle, if anyone could help I would be grateful!
You can now do this in pure CSS so no JavaScript is needed.
The new CSS pseudo-class :focus-within would help for cases like this and will help with accessibility when people use tabbing for navigating, common when using screen readers.
.login-form-field:focus-within {
border-color: blue !important;
}
The :focus-within pseudo-class matches elements that either themselves
match :focus or that have descendants which match :focus.
You can check which browsers support this http://caniuse.com/#search=focus-within
You can do like this, where you add an extra div, absolute positioned, which acts as the border, ... and no script is required.
.login-form-input {
margin-left: 20px;
width: 90%;
outline: none;
}
.login-form-label {
font-size: 13px;
font-weight: 300;
padding-left: 20px;
}
.login-form-field {
position: relative;
width: 100%;
border-radius: 0px;
height: 6rem;
box-shadow: 0px 0px 0px;
}
.login-form-field input ~ .login-form-field-border {
position: absolute;
left: 0;
top: 0;
width: 100%;
height: 100%;
box-sizing: border-box;
border: 0.5px solid grey;
z-index: -1
}
.login-form-field input:focus ~ .login-form-field-border {
border: 2px solid blue;
}
<div class="login-form-field">
<label for="email" class="login-form-label">Email:</label>
<input class="login-form-input" autofocus="autofocus" type="email" value="" name="user[email]" id="user_email">
<div class="login-form-field-border"></div>
</div>
CSS does not have native support for parent selecting. If your goal is to have .login-form-field have a blue border on focus you're going to have to rely on JavaScript to add the respective CSS.
The following CSS:
.login-form-field.highlight {
border-color: blue;
}
With the following jQuery
$('.login-form-field').hover(function() {
$(this).toggleClass('highlight');
});
Would achieve that goal. I should note that jQuery is certainly not necessary here; it's just what I prefer to use.
React with jquery:
$( document ).ready(function() {
console.log( "ready!" );
$('.login-form-input').focus(function() {
$(this).parent().css( "border", "#99f 2px solid" );
});
$('.login-form-input').focusout(function() {
$(this).parent().css( "border", "" );
});
});
Although this is an old answer. I am answering this so anyone who lands here can use just CSS to achieve this.
Use CSS3 pseudo element: focus-within
You could do:
form:focus-within {
border-color: blue !important;
}
if you want to give the border color when the input is active you can add like this:
.login-form-input:focus {
border:1px solid blue;
}

How would I add text before the numbers in odometer.js

I am using the odometer.js library and I want to add a '$' right before the display of numbers. (EX: $123,435) Does anyone know how to go about this to get it to work? I have tried adding tags and inserting it in the options section of the javascrip which is in correlation with the library, but it still will not work. I have also tried :before and :after pseudos but that is not very dynamic.
<div class="odometer" id="odometer"></div>
.odometer {
color: rgba(250,250,250,.75);
font-size: 50px;
margin-top: 100px;
background-color: #2ecc71;
text-align: center;
padding-top: 10px;
position:fixed; top: -50px; width:100%; border: 0px solid black !important;
}
.odometer:before {
content: "$";
}
This should do the trick:
.odometer-inside:before {
content: "$";
}

How to change the color of Track for RANGE Input using Jquery/Javascript?

Here`s the HTML Input Range
<input id="golden_range" type="range">
I can change the Background Color of the Range Track to "#DDD" using this CSS
#golden_range::-webkit-slider-runnable-track {
width: 300px;
height: 5px;
background: #DDD;
border: none;
border-radius: 3px;
}
#golden_range::-moz-range-track {
width: 300px;
height: 5px;
background: #DDD;
border: none;
border-radius: 3px;
}
but i'm not able to change the background color using Jquery/Javascript. Please help me with this. Here's the code i'm trying to.
$('#golden_range::-webkit-slider-runnable-track').css('background', '#000');
$('#golden_range::-moz-range-track').css('background', '#000');
According to the code in your question, I see a mistake in your syntax. In css the background color property is written as "background-color: color_hex_value". This is how your css code should look like:
#golden_range::-webkit-slider-runnable-track {
width: 300px;
height: 5px;
background-color: #DDD;
border: none;
border-radius: 3px;
}
#golden_range::-moz-range-track {
width: 300px;
height: 5px;
background-color: #DDD;
border: none;
border-radius: 3px;
}
And this is the code for jquery:
$("#golden_range::-webkit-slider-runnable-track").css("background-color", "#000");
In case you are still having doubts, give a look at these two sources for css background-color properties and Jquery css() method.
You can do this now (2020) by making use of CSS variables.
CSS
#golden_range::-webkit-slider-runnable-track {
background: var(--track-background, #ddd);
}
#golden_range::-moz-range-track {
background: var(--track-background, #ddd);
}
Javascript
document.querySelector('#golden_range').style.setProperty('--track-background', '#f00');
(should change the track background to red)
I'm doing this in Player Chrome to style the media player progress bar, using a background gradient on the track to show progress.
Bad news. I have not found a proper way to do... but I found a dirty way;
Insert a style tag in the body of the page. Of course, the content of this tag is generated with javascript:
var estilo = $("<style>").attr("id", "some_id");
//for Chrome, e.g.
var mod= "::-webkit-slider-runnable-track";
var txt= "#id_range" + mod + " {\n";
txt+= " background-color: rgb(100,100,100)\n";
txt+= "}\n";
estilo.text(txt);
$("#some_id").remove();
$("div#other_id").append(estilo);
it's ugly, slow and bad, but it works.
Add below code into your files
CSS:
#golden_range.change::-webkit-slider-runnable-track {
width: 300px;
height: 5px;
background: #000;
border: none;
border-radius: 3px;
}
#golden_range.change::-moz-range-track {
width: 300px;
height: 5px;
background: #000;
border: none;
border-radius: 3px;
}
jQuery:
$(document).on('input', '#golden_range', function() {
var rangeValue = $(this).val();
var changeRange = 20;
if(currrentRange > changeRange){
$("#golden_range").addClass("change");
}
});
Note: Please check changeRange value and change as you want.

Adding a rounded similar to border-radius to outline [duplicate]

Is there any way of getting rounded corners on the outline of a div element, similar to border-radius?
I had an input field with rounded border and wanted to change colour of focus outline. I couldn't tame the horrid square outline to the input control.
So instead, I used box-shadow. I actually preferred the smooth look of the shadow, but the shadow can be hardened to simulate a rounded outline:
input, input:focus {
border: none;
border-radius: 2pt;
box-shadow: 0 0 0 1pt grey;
outline: none;
transition: .1s;
}
/* Smooth outline with box-shadow: */
.text1:focus {
box-shadow: 0 0 3pt 2pt cornflowerblue;
}
/* Hard "outline" with box-shadow: */
.text2:focus {
box-shadow: 0 0 0 2pt red;
}
<input class="text1">
<br>
<br>
<input type=text class="text2">
I usually accomplish this using the :after pseudo-element:
of course it depends on usage, this method allows control over individual borders, rather than using the hard shadow method.
you could also set -1px offsets and use a background linear gradient (no border) for a different effect once again.
body {
margin: 20px;
}
a {
background: #999;
padding: 10px 20px;
border-radius: 5px;
text-decoration: none;
color: #fff;
position: relative;
border: 2px solid #000;
}
a:after {
content: '';
display: block;
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
border-radius: 5px;
border: 2px solid #ccc;
}
Button
Similar to Lea Hayes above, but here's how I did it:
div {
background: #999;
height: 100px;
width: 200px;
border: #999 solid 1px;
border-radius: 10px;
margin: 15px;
box-shadow: 0px 0px 0px 1px #fff inset;
}
<div></div>
No nesting of DIVs or jQuery necessary, Altho for brevity I have left out the -moz and -webkit variants of some of the CSS. You can see the result above
Use this one:
box-shadow: 0px 0px 0px 1px red;
I wanted some nice focus accessibility for dropdown menus in a Bootstrap navbar, and was pretty happy with this:
a.dropdown-toggle:focus {
display: inline-block;
box-shadow: 0 0 0 2px #88b8ff;
border-radius: 2px;
}
Visit Stackoverflow
We may see our wishes soonish by setting outline-style: auto It's on WebKits radar: http://trac.webkit.org/changeset/198062/webkit
See ya in 2030.
You're looking for something like this, I think.
div {
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
border-radius: 10px;
border: 1px solid black;
background-color: #CCC;
height: 100px;
width: 160px;
}
Edit
There is a Firefox-only -moz-outline-radius properly, but that won't work on IE/Chrome/Safari/Opera/etc. So, it looks like the most cross-browser-compatible way* to get a curved line around a border is to use a wrapper div:
div.inner {
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
border-radius: 10px;
border: 1px solid black;
background-color: #CCC;
height: 100px;
width: 160px;
}
div.outer {
display: inline-block;
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
border-radius: 10px;
border: 1px solid red;
}
<div class="outer">
<div class="inner"></div>
</div>

Firefox 88+: border-radius
From April 2021 you will be able to use a simple CSS for Firefox:
.actual {
outline: solid red;
border-radius: 10px;
}
.expected {
border: solid red;
border-radius: 10px;
}
In Firefox 88+,
<span class="actual">this outline</span>
should look like
<span class="expected">this border</span>
Current behaviour in Firefox 86.0:
Webkit: no solution
Using outline-style: auto will tell the «user agent to render a custom outline style»: see [MDN](https://developer.mozilla.org/en-US/docs/Web/CSS/outline-style(.
Webkit-based browsers will then draw the outline over the border, when you use outline-style: auto. It's difficult to style it properly.
.actual {
outline: auto red;
border-radius: 10px;
}
.expected {
border: solid red;
border-radius: 10px;
}
In WebKit browsers (Chrome, Edge),
<span class="actual">this outline</span>
should look close to
<span class="expected">this border</span>
Current behaviour in Chrome 89.0:
More information
From Firefox 88 (to be released April 20 2021), outline will follow the shape of border-radius.
The current -moz-outline-radius will become redundant and will be removed.
See MDN's entry about -moz-outline-radius:
From Firefox 88 onwards, the standard outline property will follow the shape of border-radius, making -moz-outline-radius properties redundant. As such, this property will be removed.
(Feb 2023)
As far as I know, the Outline radius is only supported by Firefox and Firefox for android.
-moz-outline-radius: 1em;
I just found a great solution for this, and after looking at all the responses so far, I haven't seen it posted yet. So, here's what I did:
I created a CSS Rule for the class and used a pseudo-class of :focus for that rule. I set outline: none to get rid of that default light-blue non-border-radius-able 'outline' that Chrome uses by default. Then, in that same :focus pseudo-class, where that outline no longer exists, I added my radius and border properties. Leading to the following
outline: none;
border-radius: 5px;
border: 2px solid maroon;
to have a maroon-colored outline with a border radius that now appears when the element is tab-selected by the user.
If you want to get an embossed look you could do something like the following:
.embossed {
background: #e5e5e5;
height: 100px;
width: 200px;
border: #FFFFFF solid 1px;
outline: #d0d0d0 solid 1px;
margin: 15px;
}
.border-radius {
border-radius: 20px 20px 20px 20px;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
-khtml-border-radius: 20px;
}
.outline-radius {
-moz-outline-radius: 21px;
}
<div class="embossed"></div>
<div class="embossed border-radius"></div>
<div class="embossed border-radius outline-radius">-MOZ ONLY</div>
I have not found a work around to have this work in other browsers.
EDIT: The only other way you can do this is to use box-shadow, but then this wont work if you already have a box shadow on that element.
Chrome 94.0+
I tested it in chrome 94.0 and it seems that the outline property honors the border-radius now.
.outline {
outline: 2px solid red;
}
.border {
border: 2px solid red;
}
.outline-10 {
border-radius: 10px;
}
.border-2 {
border-radius: 2px;
}
.outline-2 {
border-radius: 2px;
}
.border-10 {
border-radius: 10px;
}
.outline-50 {
border-radius: 50%;
}
.border-50 {
border-radius: 50%;
}
.circle {
display: inline-block;
width:50px;
height: 50px;
}
<strong>Test this in chrome 94.0+</strong>
<br/><br/>
border-radius: 2px
<span class="outline outline-2">outline</span>
<span class="border border-2">border</span>
<br/><br/>
border-radius: 10px
<span class="outline outline-10">outline</span>
<span class="border border-10">border</span>
<br/><br/>
border-radius: 50%
<span class="outline outline-50">outline</span>
<span class="border border-50">border</span>
<span class="outline circle outline-50">outline</span>
<span class="border circle border-50">border</span>
As others have said, only firefox supports this. Here is a work around that does the same thing, and even works with dashed outlines.
.has-outline {
display: inline-block;
background: #51ab9f;
border-radius: 10px;
padding: 5px;
position: relative;
}
.has-outline:after {
border-radius: 10px;
padding: 5px;
border: 2px dashed #9dd5cf;
position: absolute;
content: '';
top: -2px;
left: -2px;
bottom: -2px;
right: -2px;
}
<div class="has-outline">
I can haz outline
</div>
No. Borders sit on the outside of the element and on the inside of the box-model margin area. Outlines sit on the inside of the element and the box-model padding area ignores it. It isn't intended for aesthetics. It's just to show the designer the outlines of the elements. In the early stages of developing an html document for example, a developer might need to quickly discern if they have put all of the skeletal divs in the correct place. Later on they may need to check if various buttons and forms are the correct number of pixels apart from each other.
Borders are aesthetic in nature. Unlike outlines they are actually apart of the box-model, which means they do not overlap text set to margin: 0; and each side of the border can be styled individually.
If you're trying to apply a corner radius to outline I assume you are using it the way most people use border. So if you don't mind me asking, what property of outline makes it desirable over border?
COMBINING BOX SHADOW AND OUTLINE.
A slight twist on Lea Hayes answer
I found
input[type=text]:focus {
box-shadow: 0 0 0 1pt red;
outline-width: 1px;
outline-color: red;
}
gets a really nice clean finish. No jumping in size which you get when using border-radius
There is the solution if you need only outline without border. It's not mine. I got if from Bootstrap css file. If you specify outline: 1px auto certain_color, you'll get thin outer line around div of certain color. In this case the specified width has no matter, even if you specify 10 px width, anyway it will be thin line. The key word in mentioned rule is "auto".
If you need outline with rounded corners and certain width, you may add css rule on border with needed width and same color. It makes outline thicker.
I was making custom radio buttons and the best customisable way i've found is using pseudo elements like this: Codepen
/*CSS is compiled from SCSS*/
.product-colors {
margin-bottom: 1em;
display: flex;
align-items: center;
}
.product-colors label {
position: relative;
width: 2.1em;
height: 2.1em;
margin-right: 0.8em;
cursor: pointer;
}
.product-colors label:before {
opacity: 0;
width: inherit;
height: inherit;
padding: 2px;
border: 2px solid red;
border-radius: 0.2em;
content: "";
position: absolute;
z-index: 1;
background: transparent;
top: -4px;
left: -4px;
}
.product-colors input {
position: absolute;
opacity: 0;
width: 0;
height: 0;
}
.product-colors input:checked + label:before, .product-colors input:focus + label:before {
opacity: 1;
}
<div class="product-colors">
<input type="radio" name="cs" id="cs1" value="black">
<label for="cs1" style="background:black"></label>
<input type="radio" name="cs" id="cs2" value="green">
<label for="cs2" style="background:green"></label>
<input type="radio" name="cs" id="cs3" value="blue">
<label for="cs3" style="background:blue"></label>
<input type="radio" name="cs" id="cs4" value="yellow">
<label for="cs4" style="background:yellow"></label>
</div>
clip-path: circle(100px at center);
This will actually make clickable only circle, while border-radius still makes a square, but looks as circle.
The simple answer to the basic question is no. The only cross-browser option is to create a hack that accomplishes what you want. This approach does carry with it certain potential issues when it comes to styling pre-existing content, but it provides for more customization of the outline (offset, width, line style) than many of the other solutions.
On a basic level, consider the following static example (run the snippent for demo):
.outline {
border: 2px dotted transparent;
border-radius: 5px;
display: inline-block;
padding: 2px;
margin: -4px;
}
/* :focus-within does not work in Edge or IE */
.outline:focus-within, .outline.edge {
border-color: blue;
}
br {
margin-bottom: 0.75rem;
}
<h3>Javascript-Free Demo</h3>
<div class="outline edge"><input type="text" placeholder="I always have an outline"/></div><br><div class="outline"><input type="text" placeholder="I have an outline when focused"/></div> *<i>Doesn't work in Edge or IE</i><br><input type="text" placeholder="I have never have an outline" />
<p>Note that the outline does not increase the spacing between the outlined input and other elements around it. The margin (-4px) compensates for the space that the outlines padding (-2px) and width (2px) take up, a total of 4px.</p>
Now, on a more advanced level, it would be possible to use JavaScript to bootstrap elements of a given type or class so that they are wrapped inside a div that simulates an outline on page load. Furthermore, event bindings could be established to show or hide the outline on user interactions like this (run the snippet below or open in JSFiddle):
h3 {
margin: 0;
}
div {
box-sizing: border-box;
}

In closing, let me reiterate, that implementing this approach may require more styling than what I have included in my demos, especially if you have already styled the element you want outlined.
outline-style: auto has had full browser support for ages now.
Shorthand is:
outline: auto blue;
This let's you set a custom color, but not a custom thickness, unfortunately (although I think the browser default thickness is a good default).
You can also set a custom outline-offset when using outline-style: auto.
outline: auto blue;
outline-offset: 0px;
you can use box-shadow instead of outline like this
box-shadow: 0 0 1px #000000;
border-radius: 50px;
outline: none;
Try using padding and a background color for the border, then a border for the outline:
.round_outline {
padding: 8px;
background-color: white;
border-radius: 50%;
border: 1px solid black;
}
Worked in my case.
I just set outline transparent.
input[type=text] {
outline: rgba(0, 0, 0, 0);
border-radius: 10px;
}
input[type=text]:focus {
border-color: #0079ff;
}
I like this way.
.circle:before {
content: "";
width: 14px;
height: 14px;
border: 3px solid #fff;
background-color: #ced4da;
border-radius: 7px;
display: inline-block;
margin-bottom: -2px;
margin-right: 7px;
box-shadow: 0px 0px 0px 1px #ced4da;
}
It will create gray circle with wit border around it and again 1px around border!
