Submitted by DeveloperTutorials.com » One of the main advantages of using CSS is the large reduction in web page download time. To style text, you used to have to use the <font> tag over and over again. You probably also laid out your site with tables, nested tables and spacer gifs. Now all that presentational information can be placed in one CSS document, with each command listed just once.
Pretty good, but I think that colors are worth to bring up. Like:
#FF0000 = #F00
#00FF00 = #0F0
#0000FF = #00F
#000000 = #000
#CC33FF = #C3F
