Positioning with CSS

Hi,
I am trying to work with a site builder (confusing eCommerce) and I am using the HTML/CSS option to make my website slightly more appealing. I have copied the code from the view source of my website, but due to one reason to another:mad::mad::mad::eek::eek::p:D:D

If you're looking for some help on this I think a little more information would be helpful...link to your page and description of the problem?
