Are there any CSS standards that I should follow while writing my first stylesheet?

css

Solution

An error that beginners make quite often:

CSS is semantic as well. Try to express concepts, not formats. Contrived example:

Wrong:

div.red
{
    color: red;
}

as opposed to:

Good:

div.error
{
    color: red;
}

CSS should be the formatting companion for the concepts you use on your web site, so they should be reflected in it. You will be much more flexible this way.

Problem

I am currently working on my first website. I have no idea where to start on the CSS page, or if there are any standards that I should be following. I would appreciate any links or first-hand advise.
