CSS Doctype

So I am very new to CSS. Actually I just decided about an hour ago that I need to learn it. So I have a question:

What is the proper doctype to use in a valid CSS document?
Thanks.

Css doesnt need a doctype.
Its the whole document you give a doctype, usually for use with css go for a xhtml doctype.
So either specify xhtml1.0 ( transitional, frameset,strict,) or xhtml1.1 , or even html4.01 should validate with css

Thats what I thought. Theres alot of them so I thought maybe there was a few I didn't know about. Thanks.

css doesnt get doctypes. browsers need doctypes so they know how to correctly render the html it's given - IS strict vs transitional. they have different behaviors, CSS behanves the same everytime.

I know what doctypes do and I know CSS doesn't need one specificaly. I must have worded my question badly. Sorry about that.

No Problems Paul, good luck with the learning

Thank you.

Insted of making a new thread i thought I would post another question here (which I hope is ok):

What is the difference when I see "#content" and ".content". When do you use a pieriod, when do you use a "#"?

# is an id="bla" tag and should be unique, you use it only once in the entire page.

Period is used from classes which you will use more then once eg for text formatting, you uses the class="bla" tag in this case.

<span class="sidemenu">Some side text here</span>

Hope that helps.

It helps greatly. Thanks opserty.
