CSS troubles

I have been finding creating my cascading style sheets rather difficult  but I now feel that I am starting to understand CSS.  I have created the header for the three pages on my site and the question form to allow user of the site to ask me questions. I soon plan to begin work on the navigation aspect of my site. 

Web Space And Domain Name.

I have been searching for domain names and web space from for a few weeks now and feel I have found some appropriate sites to purchase these from. I am going to purchase my domain name from http://www.123-reg.com/ and my space from http://www.ipage.com/. I choose to use 123-reg as they are respected and have many good reviews and I choose ipage as they offer  unlimited domain hosting, unlimited badwidth and unlimited space for a cheap price.
