The @font-face rule is supported by Firefox 3.5, Safari 3.1, Opera 10, Chrome 5 and Internet Explorer 4.0. Our system is thus compatible with more than 98% of all browsers in use. For older browsers you can define a list of default web-safe font stacks.

Up until now, if you wanted to use fonts on a website you were limited to one of the dozen or so ‘web-safe’ fonts (Verdana, Times, Helvetica—you know, the ones you see everywhere on the web).
