Useful links: CSS

I have compiled a list of useful glossaries/websites that help with CSS. If you don't know what CSS is and you are trying to design a website, you probably need to start over!

W3Schools

http://www.w3schools.com/css/
W3 Schools has the best online resource for coding. Not just for CSS!
Make sure you keep your knowledge up with new versions of CSS over the years.

CSS Validator
http://jigsaw.w3.org/css-validator/
If your CSS isn't fully compliant, its inevitable that some of your users (if not all) will not experience your website the way you want them to. TESTING PEOPLE, TESTING!

CSS Basics
http://www.cssbasics.com/
This wont teach you everything you need to know, but it will certainly help reinforce the 'basics' of CSS.

Advanced CSS
http://www.yourhtmlsource.com/stylesheets/advancedcss.html
This is a blog that will spit out some more advanced techniques now and then.
