What are the advantages of css over HTML? I know one is css web sites are more SEO friendly. This is because all the styling informations are kept in a separate page and all texts in a separate page. So Search Engines find it more easy to look for the content. Do you know any more advantages?

I found one website about css advantages and there is so much interesting and all information is only about css nice website try you too :http://www.quackit.com/css/tutorial/css_advantages.cfm

html include css, when the page first time load, it will be quickly.
so it's often use in home page.
