The site http://www.wikimedia.org.es/ is just a MediaWiki install with a custom
skin. The main page blocks (Actividades, Participa, Dona, Blog and the
slideshow) are achieved with a tag which outputs the needed html.

However, there is a bug in the css, which relies on some element of the custom
skin for proper placement. Compare
http://www.wikimedia.org.es/wiki/Portada?useskin=wmes (Good: Actividades,
Participa & Dona at the left) with
http://www.wikimedia.org.es/wiki/Portada?useskin=vector (Wrong: Actividades,
Participa & Dona appear on top of the slideshow).

Figure out the wrong rules and provide a patch for fixing the issue, so it
works on any skin. Both the html (the php file) and the css can be changed.

See the files at bug 57563.

Since this extension is not in gerrit, the patch shall be provided on 
bug 57563.
