EW handles CSS quite well, and has some built in page templates for you to use.
However, I prefer to make my own templates, a basic CSS layout is pretty easy to design (if you decide to ignore older browsers). There are plenty on the net and in the CSS forum here that you can try.
EW provides some excellent tools for learning CSS, but if it does occasionally display things wrongly! But if you install Firefox to preview pages you can make sure things are displayed as they should be.
