So i learned the ropes of doing sites in Dreamweaver, and almost 95% of my css is filled with lots of ID tags, is this a bad practice or doesn't matter? I haven't found the need for Classes. are classes used as inline? or block level? when do you use a class.

Classes are for elements that will be used multiple times in an document. IDs are for single use only.
