Please add more guidelines on CSS USage and semantic HTML

[taitems]

Is there anything in particular you're after, or should I just flesh out these sections more?

[krhebbar]

importance of semantics, code HTML (semantic) first and add css(presentation) later. not to code HTML for presentation.
Any HTML CSS design patterns, good practices.

For images as list bullets, I suggest adding them via CSS eg.:
ul {
list-style-image: url(tips.gif);
}
rather than " ". That way when you want to change the bullets, you just change it in the CSS.
