Open Designs

Although Web pages are usually regarded as content, there can be a fair amount of code behind them too in the form of scripting and cascading style sheets (CSS). This means that there is a need for shared code in these areas, and the Open Design community aims to help out on the CSS side.

As an aside, it's interesting to note that the majority of stylesheets there use a Creative Commons licence, rather than the GNU GPL, say: this suggests people think of the code more as a form of content in this context. (Via James Tyrrell.)
