It's easy to learn CSS if you understand the concept of basic object orientated programming, you just write the html doccument and then later add the styles to the objects.
There's nothing too hard about it, just need to learn some different commands other than font, size, B, align, etc.

Elements like body, p, h1, etc don't need an identifier like class or ID.
eg.

body
{
 background:#444444;
 color:#ffff00;
}

p 
{
 padding:0px;
 margin:0px;
}
h1 
{
 text-align:right;
 font-weight:normal;
}

Basically if an object is used once only in your pages, make it an ID (#something).
If it's going to be used on the one page more than once make is a class (.something).
Then style the ID's and classes with what you want like.

eg.

#anId
{
 color:#ff00ff;
 background:#ffffff;
 border:4px solid #ff0000;
}

.aClass
{
 color:#000000;
 background:#ffffff;
 border: 4px solid #ff0000;
}

Basically if you are getting rid of tables, your HTML doccument should make sense without any styles.
If you look at a site done with tables and no stylesheet it will most likely be unintelligible.
But a site made with lists and divs instead should still be functional without the style sheet.

A good thing about CSS is that if you are using an external style sheet, you can change the appearance, graphics, background, etc. of your entire website of 10,000 pages by uploading one file.
