I'm looking for an advice about work with SVG images, respectively icons.
What I've tried
If I'm using PNG icons, the CSS is like:
elem:after {background: url('icon.png'); ...}
I've tried the same way
elem:after {background: url('icon.svg'); ...}
but it isn't what I'm looking for. This solution lose advantages of SVG icons (they're small and blured, fuzzy).
What I have
I've generated this code online using Icomoon app.
<svg aria-hidden="true" style="position: absolute; width: 0; height: 0; overflow: hidden;" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<defs>
<symbol id="icon-love" viewBox="0 0 33 32">
<title>love</title>
<path d="M32.916 15.597c0.604-0.66 ..."></path>
</symbol>
<symbol id="icon-shop" viewBox="0 0 34 32">
<title>shop</title>
<path d="M17.148 27.977c-..."></path>
</symbol>
</defs>
</svg>
<svg class="icon icon-shop">
<use xlink:href="#icon-shop"></use>
</svg>
My question
Is it semantically correct to put icons into HTML markup, instead of putting them into CSS?
Across whole website there is about 60 icons, any unique, any are repeated more times. Generated markup above has about 50kB.
Can I put all icons into general layout template and load them all in whole website, or include just icons I use in the page?
Here I've found How to change color of SVG image using CSS (jQuery SVG image replacement)? (3 years ago), but don't know if it's the right way.How to cache SVG properly? Is it posible when I use it like I'm writing above?
I read many articles, but not definitely sure how to do that best way.
Thanks for advice.
