Replacing Font Awesome in heading with local SVG - svg

Question

I'm using this snippet for adding a Font Awesome icon in front of H1 headings:
h1:before {
content: "\f192 ";
font-family: "FontAwesome";
color: blueviolet;
}
How to adapt it for using a locally served (on site's server) SVG icon instead?
(that is uploaded in WP Media Library and using SVG Support plugin)

Answer 1

If your icon needs to remain a separate file, you can set it as a background image.
h1:before {
display: inline-block;
background-image: url(resources/icon.svg)
}
Otherwise you can embed your icon as a data url.
h1:before {
display: inline-block;
background-image: url(data:image/svg+xml,...etc...)
}
Update
Working example:
h1:before {
content: " ";
display: inline-block;
width: 0.7em;
height: 0.7em;
background-image: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 10 10'%3E%3Ccircle cx='5' cy='5' r='5'/%3E%3C/svg%3E");
background-size: contain;
background-repeat: no-repeat;
}
