I know where to go to edit the CSS thing. But I need to know what to do when I get there, i know how to change pictures, background, but i gotta know how to change the layout.

How i change the layout?
How i make my menu horizontal?
How i put buttons in my menu where it has text links?
How i put adds in the right or left side of my website?
How i use all the empty spots for the entries?
How i get more workspace (move the margins, so that i can stack more stuff in)

right now, that's all i can think of, answer these questions simply and if i gets the answers, i would stop askin questions for a while. thank you,
please don't get me wrong, i'm not trying to spam, i really needs the answers.

thank you

update:

if that picture that i just sent is hard for you to understand, let me know, i'd make it easier for you by putting in a better one.. but please answer these.

I suggest that you use Templates Builder ( http://forum.ucoz.com/forum/5-3045-1 ) if you are going to create a custom template.

The things you are asking require HTML and CSS skills. Besides they are too general.
