I want to place some SVG images before some selected elements. I am using jQuery but that is irrelevant.
I would like to have the :before
element to be as:
#mydiv:before {
content: '<svg.. code here</svg>';
display: block;
width: 22px;
height: 10px;
margin: 10px 5px 0 10px;
}
If I do it as shown above, it just display the string. I checked the specs and there seems to be some restrictions on what content can be. Is there a work around to this restriction? Only the content css is relevant to my question.

Convenient tool for SVG encoding url-encoder
Be careful all of the other answers have some problem in IE.
Lets have this situation - button with prepended icon. All browsers handles this correctly, but IE takes the width of the element and scales the before content to fit it. JSFiddle
#mydiv1 { width: 200px; height: 30px; background: green; }
#mydiv1:before {
content: url("data:url or /standard/url.svg");
}
Solution is to set size to before element and leave it where it is:
#mydiv2 { width: 200px; height: 30px; background: green; }
#mydiv2:before {
content: url("data:url or /standard/url.svg");
display: inline-block;
width: 16px; //only one size is alright, IE scales uniformly to fit it
}
The background-image
+ background-size
solutions works as well, but is little unhandy, since you have to specify the same sizes twice.
The result in IE11:
To extend further this topic. In case you want to add Font Awesome 5 icons you need to add some extra CSS.
Icons by default have classes svg-inline--fa
and fa-w-*
.
There are also modifier classes like fa-lg
, fa-rotate-*
and other. You need to check svg-with-js.css
file and find proper CSS for that.
You need to add your own color to css icon otherwise it will be black by default, for example fill='%23f00'
where %23
is encoded #
.

<h1>Lorem Ipsum</h1>
_x000D_
.myDiv {
display: flex;
align-items: center;
}
.myDiv:before {
display: inline-block;
content: url(./dog.svg);
margin-right: 15px;
width: 10px;
}
You can add the SVG as background-image
of an empty :after
or :before
.
Here you go:
.anchor:before {
display: block;
content: ' ';
background-image: url('../images/anchor.svg');
background-size: 28px 28px;
height: 28px;
width: 28px;
}
#mydiv:before {
content: url("data:image/svg+xml; utf8, <svg.. code here</svg>");
display:block;
width:22px;
height:10px;
margin:10px 5px 0 10px;
}
make sure your svg doesn't contain double quotes, and uriencode any # symbols.
Making use of CSS sprites and data uri gives extra interesting benefits like fast loading and less requests AND we get IE8 support by using image/base64:
HTML
<div class="div1"></div>
<div class="div2"></div>
CSS
.div1:after, .div2:after {
content: '';
display: block;
height: 80px;
width: 80px;
background-image: url(data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20version%3D%221.1%22%20height%3D%2280%22%20width%3D%22160%22%3E%0D%0A%20%20%3Ccircle%20cx%3D%2240%22%20cy%3D%2240%22%20r%3D%2238%22%20stroke%3D%22black%22%20stroke-width%3D%221%22%20fill%3D%22red%22%20%2F%3E%0D%0A%20%20%3Ccircle%20cx%3D%22120%22%20cy%3D%2240%22%20r%3D%2238%22%20stroke%3D%22black%22%20stroke-width%3D%221%22%20fill%3D%22blue%22%20%2F%3E%0D%0A%3C%2Fsvg%3E);
}
.div2:after {
background-position: -80px 0;
}
For IE8, change to this:
background-image: url(data:image/png;base64,data......);
