[What are XHTML and CSS Valid links on a Webpage??]

Hi Jerry,

When you have completely valid CSS and XHTML, you will get a green message when you click on those buttons.

 

Go here: http://jigsaw.w3.org/css-validator/

and type in www.yahoo.com

 

You should get a correct validation message. This is not required, but is often regarded as good practice.
