I just styled a CSS box based on Dan Cederholm's Bullet Proof Box. (Bulletproof Web Design : Improving flexibility and protecting against worst-case scenarios with XHTML and CSS) I appreciate his practical and reasoned approach to explaining best practices in CSS design. The box will grow vertically (to a point) as browser text size is increased. At some point I may try his horizontal fluid box too.

Attached are my my css, html, jpg, psd, and ai files. Feel free to use them how you like.
