Thanks again for your time to review my site.
I am wondering how many web sites have a 100% valid code and about its importance.
Type in google.com. W3 shows 30 errors.
Of course it’s a good idea to fix the code in a reasonable time.
Bright colorfull graphics are looking better on a black background then on a white one.
Pages that contain mainly text are better done with a white background.
Good luck all!
