There are three levels of CSS—two actual specifications and a third level in recommendation status. Notable differences exist between the two standards and the third recommendation. The main differences between the three levels are as follows:
✦ CSS1 defines basic style functionality, with limited font and limited positioning support.
✦ CSS2 adds aural properties, paged media, better font and positioning support.
Many other properties have been refined as well.
✦ CSS3 adds presentation-style properties, allowing you to effectively build presentations (think Microsoft PowerPoint) from Web documents. Keep in mind that you don’t have to specify the level of CSS you are using for your documents, but you do have to be conscientious about what user agents will be accessing your site. Although most browsers support CSS, the level of support varies dramatically. It’s always best to test your implementation on target user agents before widely deploying your documents.
