First of all I would separate the CSS from the Markup and then check them with the validators then link the CSS to the Markup.
First the
Markup Validator
http://validator.w3.org/
And then the
CSS Validator
http://jigsaw.w3.org/css-validator/
I will be grateful if you would review my sites please
They were both done with each of the hosts WYSIWYGs and need to be recoded into HTML5 and CSS3 format
The first link I am currently working on as this is the top priority so would appreciate any and all feedback...
