<!-- We were using FontAwesome for our icons, but then found that some clients have blocked the downloading of custom fonts.
To resolve this issue, we had to switch all our fonts to svgs instead.
Someone else has already converted FontAwesome to svgs/pngs, so we started with that repo ( https://github.com/CodeCharmLtd/Font-Awesome-SVG-PNG )
We decided to put our svgs in a sprite sheet and after a decent amount of trial and error, got things working.
Here's a code snippet; hope this helps!
More about this issue at https://github.com/FortAwesome/Font-Awesome/issues/3203

<!-- SVG sprite sheet included once on the page.
It it hidden, but needs to be present so that other svgs can refer to these paths.-->
