cosmofont creates CSS stylesheets so you can use custom fonts in your projects. Use your own font files or use cosmofont to get some of the most popular typography on the web from Google Fonts. cosmofont supports .eot, .tff, and .woff file types. Use Data URIs to embed fonts inline so you can use your webfonts offline!
