I'll try to remember to answer when I'm home. I have this working in a private repo so I'll make it public. Just checked it on my iPhone where it doesn't seem to work in Safari though so it's possible the support is not stellar. For sure worked in Firefox on my desktop though.

Maybe the CSS properties require the vendor prefix (i.e. -webkit-) to work in Safari. The same could be true for other browsers.
