WordPress.com introduced "Custom Design," a powerful new tool that combines easy to use, code-free font selection from Typekit and a beautiful CSS editing interface.
Both -- Fonts and CSS--are avilable under Appearance ? Custom Design in the dashboard.
Font Editor provides a visual preview of your blog with over 50 gorgeous premium Typekit fonts-from foundries like Mark Simonson, exljbris, FontFont, and the League of Moveable Type-and allows you to easily modify the size and style of your fonts. It works with all themes, no coding skills required!
With Custom Design upgrade comes the ability to manage all your Typekit fonts settings from within your dashboard; you no longer need to make a roundtrip to Typekit and back to update the fonts on your blog.
CSS editing tool received a visual refresh with its merge into the Custom Design upgrade. If your site already has custom CSS enabled, it'll continue to work as it does now, and visitors will see no changes to your design. Furthermore, you've been upgraded to new Custom Design package for free, so you now have full access to all the new features, including the Font Editor.
Custom Design costs just $30 a year, and both features include a free preview so you can try them out first.
