<p>Changing a font is much more work (and needs more knowledge) than changing a svg. For crossbrowser support we need eot and woff font. With a svg we need a png as a fallback.<br>
I would use a media query (like my code above) or a <a href="https://github.com/supports" class="user-mention">@supports</a> rule (<a href="http://caniuse.com/#feat=css-featurequeries">http://caniuse.com/#feat=css-featurequeries</a>). </p>
