Google is taking on projects like sIFR and Cufón with their new Google Font API. A simple line of JavaScript lets you load a font family from their directory of open source fonts, allowing you to safely reference it within your CSS.
Here is an example:
<link rel="stylesheet" type="text/css" href="http://fonts.googleapis.com/css?family=Cardo"> <style type="text/css"> body { font-family: 'Cardo', serif; font-size: 24px; } </style>
It’s simple, and it looks like it works cross-browser pretty much. Hopefully we’ll be seeing more supported fonts in the future. And please, don’t abuse Lobster until it becomes the next Comic Sans.
