<span class="dropcap">N</span>ight Tabs (formerly TrueTabs) is an extensive CSS3
Tabbed Content snippet. It started out small as a typical CSS Tabs snippet, but
I have expanded it greatly. It offers many features, and can be easily modified
to fit your needs. Some of the features include: Cross browser support, preset animations,
colors, and layouts, a responsive grid system, and a typography set, among other
things.</p>
