You can go here for information on styling properties:
The page also has a try out section where you can see (or not see) these properties in action.
Some quick notes:
1. There is no such term as "hide" for visibility. Correct term is "hidden".
2. IE7's interpretation of z-index is "questionable", so you have to be a bit more careful with it. Not sure what the consensus with development, but my company is dropping support for IE7. Others may not be as lucky, so keep a lookout.
3. That link I provided doesn't specifically mention it, but border-collapse only deals with the <table> element, or classes/ids in reference to a <table> element. So you can't create a div with borders, use "border-collapse" on the div element, and expect it to do something.
