CSS Text/Font Question

Well im designing my site, anyway iv got the main design for the site working fine. Now its the hard part of text/text colour/text size/text font etc. Although when doing it in CSS the text remains the same for the whole site.

My Question is: “Is there code that you can add into the CSS script that will make it so it will use one type of font/size/colour for one table/cell and in another table/cell it will use a different colour/size/font??”

In other words asigning different text/font to different table/cells??

Cheers Ben :s:
