Hi,

The example that I've seen is this:

In this web: http://en.wikipedia.org/wiki/The_Matrix_%28franchise%29 at the end is invoqued the {{Matrix}} template.

This template calls the NavBox template. Is in this las template where we can read:

<td class="navbox-group" style="{{{basestyle|}}};{{{groupstyle|}}};{{{group2style|}}}">

The 'basestyle' has a value but I don't understand where comes from. Thanks everybody :)
