Hi Dirk,

Apologies, but I'm not a php expert.

You don't need any knowledge in PHP. CSS is style sheet language.

I do not know where I can find the ccs file.

It is located at: /themes/default/, if you use the default template.

Please note: To reduce bandwidth, MLF use the - hard to read - style.min.css. A user friendly (uncompressed) version is given by style.css. If you edit the style.css, you have to modify the main.tpl in line #12, too.

regards
Micha
