how to create inline style with :before and :after
Solution 1
You can't. With inline styles you are targeting the element directly. You can't use other selectors there.
What you can do however is define different classes in your stylesheet that define different colours and then add the class to the element.
Solution 2
You can, using CSS variables (more precisely called CSS custom properties).
- Set your variable in your style attribute:
style="--my-color-var: orange;"
- Use the variable in your stylesheet:
background-color: var(--my-color-var);
Minimal example:
div {
width: 100px;
height: 100px;
position: relative;
border: 1px solid black;
}
div:after {
background-color: var(--my-color-var);
content: '';
position: absolute;
top: 0;
bottom: 0;
right: 0;
left: 0;
}
<div style="--my-color-var: orange;"></div>
Your example:
.bubble {
position: relative;
width: 30px;
height: 15px;
padding: 0;
background: #FFF;
border: 1px solid #000;
border-radius: 5px;
text-align: center;
background-color: var(--bubble-color);
}
.bubble:after {
content: "";
position: absolute;
top: 4px;
left: -4px;
border-style: solid;
border-width: 3px 4px 3px 0;
border-color: transparent var(--bubble-color);
display: block;
width: 0;
z-index: 1;
}
.bubble:before {
content: "";
position: absolute;
top: 4px;
left: -5px;
border-style: solid;
border-width: 3px 4px 3px 0;
border-color: transparent #000;
display: block;
width: 0;
z-index: 0;
}
<div class='bubble' style="--bubble-color: rgb(100,255,255);"> 100 </div>
Solution 3
The key is to use background-color: inherit;
on the pseudo element.
See: http://jsfiddle.net/EdUmc/
Solution 4
If you really need it inline, for example because you are loading some user-defined colors dynamically, you can always add a <style>
element right before your content.
<style>#project-slide-1:before { color: #ff0000; }</style>
<div id="project-slide-1" class="project-slide"> ... </div>
Example use case with PHP and some (wordpress inspired) dummy functions:
<style>#project-slide-<?php the_ID() ?>:before { color: <?php the_field('color') ?>; }</style>
<div id="project-slide-<?php the_ID() ?>" class="project-slide"> ... </div>
Since HTML 5.2 it is valid to place style elements inside the body, although it is still recommend to place style elements in the head.

Solution 5
I resolved a similar problem by border-color: inherit
, see:
<li style="border-color: <?php echo $hex ?>;">...</li>
li {
border-width: 0;
}
li:before {
content: '';
display: inline-block;
float: none;
margin-right: 10px;
border-width: 4px;
border-style: solid;
border-color: inherit;
}

I generated a bubble chat thingy from http://www.ilikepixels.co.uk/drop/bubbler/
In my page I put a number inside of it
.bubble { position: relative; width: 20px; height: 15px; padding: 0; background: #FFF; border: 1px solid #000; border-radius: 5px; } .bubble:after { content: ""; position: absolute; top: 4px; left: -4px; border-style: solid; border-width: 3px 4px 3px 0; border-color: transparent #FFF; display: block; width: 0; z-index: 1; } .bubble:before { content: ""; position: absolute; top: 4px; left: -5px; border-style: solid; border-width: 3px 4px 3px 0; border-color: transparent #000; display: block; width: 0; z-index: 0; }
I want the
background-color
of the bubble to change according to the number inside of it viargb
so if my div is
<div class="bubble" style="background-color: rgb(100,255,255);"> 100 </div>
I want the color to be
rgb(100,255,255)
The thing is this doesn't affect the triangle.
How do I write the inline css so it will include the :before and :after?

jebbie about 6 years@NickGinanto sure you can - it just won't work :D your fighting here with browser internals, you cannot reinvent the weel with a language laying on top of that...

Diego Pamio over 5 yearsgreat solution! It was perfect for my situation (aplying conditionals in liquid that affect styles).

-
Nathan Arthur almost 5 yearsYup, if you need to support IE, you'll want to limit custom properties to use cases that won't cripple website functionality for IE users. In other words, use progressive enhancement.

Jay Edwards almost 4 yearsgood answer. inheritance can be very very handy with :after when you want things like arrows made out of borders with parent-dependent colors...
