I just installed WordPress via cPanel's automatic installation function, filled out the required information and after logging in to the admin page checked that my site was live and looked to be functioning as it should be. I then proceeded to check for validation errors on the http://jigsaw.w3.org/css-validator/ site to find that I have 89 errors and 146 warnings. So out of curiosity I switched my theme to Twenty Ten and did the validation check again to find 8 errors and 62 warnings. This is a brand new installation and nothing has been done with the site yet - why am I getting so many errors? How do I fix this or is it normal? If so, whats the point in validating a site based on the Twenty Eleven/Ten theme when they are apparently flawed to begin with? Starting a brand new WP site with so many errors has me very confused. My worry is that I'll be building my child theme on a problematic theme that will cause nothing but issues down the road. I'm new to WP and kind of lost at what to do next, any help would be much appreciated!
