I am allergic to CSS, but I would also like to be able to tweak a few details (like align the navigation menu to the right instead of the left, and such).

Is there any general guide to CSS that I could use? I can usually understand code that is given and tweak as needed, but I am not sure where to start with this.

In the Guides section. Scroll down to “CSS Framework”

Thanks. That will surely be useful. I still can't figure out how to right-align the menu without the whole header. Any hint?

You would have to override the “float” of the menu items, which are <li> elements. However setting them float:right would also reverse the order of the menu. Not a good idea. There is also JavaScript acting on the menu, which can mess things up. I wouldn’t do these kind of “tweaks” unless it serves a clear need and you are absolutely sure you know what you are doing. 

Hum... I am not that sure, but I wanted to emulate my existing website navigation so it would not be so different for my current visitors/members. I guess I know just enough to be dangerous 😞
