Site to Check Code (HTML) and (CSS)

[jimmy0225]

Hi,

Iwas wondering what sites you use to check if your website has clean HTML & CSS code.

I know there are many for load time.

I remember coming across one that checked HTML and CSS and also listed the errors.

Thanks in advance for any input

W3C Schools CSS Checker & Markup Validation Checker

I use these religiously for every audit I perform.  I run both on the home page, and at least one page from every other primary template on a site.  I then run them both on at least one or two other highly visited pages that have questionable page speeds as well.
