Google Web Fonts on HTTPS pages on Chrome

Create a schema agnostic url

Change http://fonts.google... to //fonts.google...

Drop the http: or https: from the front, the browser will use whichever schema you’re currently using on the site.

You may request resources using https from http, but not the other
way round. An alternative to the above solution (and probably best practice) is to just always use
https if it’s available (which it must be if you’re using this style
of link, otherwise there no point in it anyway).
