OK, I got it Thanks, but I still have some issues!
1- It looks like it does not like another mod I have installed since a long time ago: Microstats:

See picture included (use the zip to see it full size).
Usually, the line appears only at the complete bottom of my home page but now it appears under the additions I made on my header with your hack! I have no idea why. I remove your code and that other line also disappear! Wow, no idea why!!
2- Still no answers how to translate the menu item. Can I use phrases?
3- Also, I tried you code for changing the color when my mouse goes over a menu item and it just does not work.
4- Finally, how to change the background color of the banner (which covers the whole width of the page under the tab buttons) to make it the same as my home page (like you see just above the banner, kind of grey-blue)? What settings must I change in your code?
