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 :)
