Am having trouble with my website and css. When I validate I get 67 errors in syntax. I have gotten it down to 52 but still need help getting rid of the others.
Anywhere I can get some help with that?

Also a question, if I design another website with the same domain name can I
change one (the good one) for the other (the bad one)? Can I design one in a
website builder, upload it, and then substitute one for the other?
