What codes can be there be in a style sheet? does all css or is there certain codes?

Not quite sure what youre asking but yes, all CSS codes go in a style sheet and nothing else should be in it.

css is used to ''pretty up'' a webpage, and the codes that can be used are font styles, scroll bar, body styles, all that sort of thing. a style sheet has to be all css. Theres a page on this website all about it :)

This site's css page has a lot of examples:

css chooses what your site looks like, like what color or size the text and links and scrollbar are.

there are codes for what you want ur tables to look like, codes for your background, codes for everything.

Is that what you mean? :lolol:

Ultimately CSS is going to be used to separate formatting entirely from content so one can type in content into "divisions" on one document and have the formatting set up on a separate page (which can also be applied to numerous, whether 10's, 100's, or 1000's, of content documents such that to change the look or feel of the site with all its pages, one only has to make changes to the style sheet or formatting page). There are many HTML tags and attributes that have been designated as "deprecated" or obsolete by the W3C and future browsers will eventually not be able to read or render them on a page {probably years into the future but for many on this forum, certainly within their lifetime or working years; those looking at computer programming and web design occupations will need to be able to set up a page as doctype XHTML "strict" (meaning no use of deprecated tags and attributes) to meet the criteria which will be required in the future}. I personally am just starting to learn CSS to a full application level, even as "old" as I am haha... one of these days I'll retire from the Navy and hope to get one of those jobs somewhere doing that sort of thing. The wife wants to move somewhere "warm" in the winter and I think I'll have to do the second career thing to be able to do that.
