the Typecast app

Typecast by FRONT is a tool for creating your CSS code with webfonts directly in the browser with a true WYSIWYG view. It’s an online service for developing the typographic layout of websites directly in the browser. You can style your headlines and paragraphs in an easy and intuitive way, without the need for writing and changing CSS values over and over again. Once you are satisfied with the results you can just grab the CSS code and put it in your project.

The Typecast app is currently in Beta, but you can already play with fonts from Typekit, Fontdeck and the Google Webfonts directory.
