Any way to use SVG Sprite from CSS? - css

HTML:
<svg>
<use xlink:href="/assets/images/icons-sprite.svg#icon-name"></use>
</svg>
SVG sprite:
<svg width="0" height="0" class="hidden">
<symbol xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24" id="icon-name">
<path ... fill="currentColor"></path>
</symbol>
</svg>
Is there any way to use SVG sprite from CSS
Like this
<div class=“icon”></div>
.icon {
background-image: “/assets/images/icons-sprite.svg#icon-name”
height: 30px
}

I’m using the technique for including SVGs described here whereby you create a doc that looks something like this…
<svg xmlns="http://www.w3.org/2000/svg">
<symbol id="arrow-left" viewBox="0 0 10 16">
<path d="M9.4 1.4L8 0 0 8l8 8 1.4-1.4L2.8 8z"/>
</symbol>
<symbol id="arrow-right" viewBox="0 0 10 16">
<path d="M0 14.6L1.4 16l8-8-8-8L0 1.4 6.6 8z"/>
</symbol>
</svg>
Include it in the top of your HTML and then insert the SVG icons in your markup like this…
<svg class="arrow-right">
<use xlink:href="#arrow-right" />
</svg>
It’s easy and works great. However, I’m trying to use the same icons in my CSS pseudo classes :before and :after using an empty content attribute and the SVG in the background. Something like this…
.title:after {
float: right;
width: 16px;
height: 10px;
content: "";
background: url('#arrow-right');
}

SVG styling problems with <use>

I'm trying to change, with CSS, the size and color of an SVG element that's being rendered with <use>. The SVG in question:
<svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" fill="none" viewBox="0 0 24 24">
<path fill="#000000" fill-rule="evenodd" d="<all the actual svg path info>" clip-rule="evenodd"/>
</svg>
I do not have permission to change the contents of the SVG itself.
The way I'm using the SVG:
<svg>
<use xlink:href="#myIcon"></use>
</svg>
I've fought with this for hours, read through a pretty comprehensive article on the subject, and I still haven't had any success. I've tried applying classes to both the use element and the outer svg element, as well as referencing the path element inside. I can't seem to do anything to override the provided styles. How can I change the width, height, and fill color with this arrangement?
For the size it's easy if you correctly set the viewBox and then you adjust the width/height.
For the coloration you can rely on blending mode since the color of the SVG is black.
.icon {
display: inline-block;
background: #fff;
position: relative;
}
.icon::after {
content:"";
position:absolute;
top:0;
left:0;
right:0;
bottom:0;
background:var(--c);
mix-blend-mode:lighten;
}

Save svg as a image with svg format then add the color and width or whatever you want to your img then add this to the html file as a img tag and display: none the svg code.
If you can't reach the html code then you can't do anything.

SVG sprite in CSS content attribute

I have a given svg-sprite:
<svg xmlns="http://www.w3.org/2000/svg" style="display: none;">
<symbol id="envelope" viewBox="0 0 512 512">
<path d="M502.3 190.8c3.9-3.1 ...."></path>

</symbol>
</svg>
Now i would like to add the second symbol (menu-2) to the ":after" of mydiv
mydiv:after {
content: url("somehow add menu-2 from svg sprite");
}
How can i reference it?
mydiv:after {
content: url(http://server/sprite.svg#menu-2);
}
where -
http://server path to the server or to the folder where the svg file is stored
#menu-2 - The called part of the sprite

Fill Colour on <use> Element For a <symbol> Isn't Changing Colour

I'm trying to change the fill colour on an SVG symbol when it is inside a <use> element. Because there are going to be multiple instances of the symbol on the page, I can't do this is the <symbol> element, because the different instances of <use> will be different colours.
I've can't seem to get it work though. In the example below I would like to the bottom instance to be a blue twitter icon.
In the CSS I've done #bottom-twitter svg path {fill:blue;} which doesn't work. And I can't seem to get anything to work.
Any help would be amazing.
#box1 {
height: 5rem;
width: 5rem;
}
/* NOT WORKING */
#bottom-twitter svg path {
fill:blue;
}
<svg id="twitter" style="display: none;">

The problem is the fill="#000" in the svg path. Remove that or just change it to be the color you want.

#bottom-twitter {

SVG Sprite with <use> xlink in CSS ::after

I’m using a SVG sprite like this in the body:
<svg xmlns="http://www.w3.org/2000/svg" style="display: none;">
<symbol id="bars" width="1792" height="1792" viewBox="0 0 1792 1792">
<path d="M1664 1344v128q0 26-19 45t-45 19h-1408q-26 0-45-19t-19-45v-128q0-26 19-45t45-19h1408q26 0 45 19t19 45zm0-512v128q0 26-19 45t-45 19h-1408q-26 0-45-19t-19-45v-128q0-26 19-45t45-19h1408q26 0 45 19t19 45zm0-512v128q0 26-19 45t-45 19h-1408q-26 0-45-19t-19-45v-128q0-26 19-45t45-19h1408q26 0 45 19t19 45z"/>
</symbol>
</svg>
If I need the symbol, I call it like this:
<svg class="icon left bars" style="fill: #000;">
<use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#bars"></use>
</svg>
Now I need this SVG in a CSS ::after. I know that you can use a SVG as background image in the ::after but it won’t work with use:
.element::after {
background: url('data:image/svg+xml;utf8,<svg class="icon left bars" style="fill: #000;"><use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#bars"></use></svg>') no-repeat;
//background: url("data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' width='61' height='41' fill='#000' stroke='none'><path d='M0,0 6,10 L12,0 L0,0 Z'></path></svg>") no-repeat;
content: "";
display: block;
height: 16px;
width: 16px;
}
Demo: JSFiddle
Is there anyone who got this working?
.element::before {background-image:url("data:image/svg+xml;charset=UTF-8,<svg xmlns='http://www.w3.org/2000/svg' width='100%' height='100%' viewBox='0 0 75.33 68.119'>\ <polygon fill-rule='evenodd' clip-rule='evenodd' fill='red' points='8.125,11.865 75.33,0 73.794,37.574 70.938,68.119 0,64.603 '/>\ </svg>"); content:""; display:inline-block; width:75.33px; height:68.119px;}
<div class="element"></div>
However it only works on non-IE browsers, a shame as you could turn it into a mixin in less/sass so you dont bloat your working css.
I got it from

And also worth a read https://manu.ninja/inline-svg-how-i-learned-to-stop-worrying-and-love-gzip/

Responsive clip-path with inline SVG

On an element with a background (image or solid color don't really matter):
<header id="block-header"></header>
I am trying to apply a clip-path using SVG. To achieve this, I am putting SVG inline into the same element like this:
<header id="block-header">
…
<svg width="100%" height="100%" viewBox="0 0 4000 1696" preserveAspectRatio="none">
<defs>
<clipPath id="myClip">
<path d="M0 1568.18V0h4000v1568.18S3206.25 1696 2000 1696C984.37 1696 0 1568.18 0 1568.18z"/>
</clipPath>
</defs>
</svg>
…
</header>
You can run the code snippet below or check the JSFiddle. You can see original SVG image (in black) put inline, having curviness along the bottom and being responsive. In contrast, the red rectangle shows the same image applied (or, rather, not applied) as a clip-path.
I guess I misunderstand either viewBox or preserveAspectRatio attributes though can not find what is exactly wrong here. Any help would be appreciated.
#block-header {
background: Red;
min-height: 100px;
-webkit-clip-path: url(#myClip);
clip-path: url(#myClip);
}
<h1>SVG image</h1>

</clipPath>
</defs>
</svg>
</header>
References to SVG clip paths are to the clip path definitions themselves and the dimensions or other attributes of the <svg> are meaningless in this context.
What is happening in your example is that you are applying a 4000 px wide clip path to your header. Which is probably only of the order of 900 px wide. So the curvature isn't visible.
If you want a responsive clip path, you should define it using clipPathUnits="objectBoundingBox".
#block-header {
background: Red;
min-height: 100px;
-webkit-clip-path: url(#myClip);
clip-path: url(#myClip);
}
<h1>SVG image</h1>
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100" viewBox="0 0 1 1" preserveAspectRatio="none"><path d="M0,0 1,0 1,0.9 C 1,0.9, 0.77,1, 0.5,1 0.23,1, 0,0.9,0,0.9z"/></svg>
<h1><code>clip-path</code> using the same SVG</h1>
<header id="block-header">

</clipPath>
</defs>
</svg>
</header>
