HTML 5 & CSS 3
CSS (Cascading Style Sheets) allows web authors to apply styles to their web pages. More importantly, CSS enables them to do this independently of the HTML that makes up each web page. Therefore, as a web author, you can code your HTML without having to be concerned with what each HTML element is going to look like. You can change the look later using CSS. You'll find a wealth of information about CSS right here on Quackit. Read the CSS Tutorial, learn all the CSS properties that you can use, or just go straight to the code for some good old "cut & paste"!
