These aren't organized in any way for now. Maybe when I collect enough of them, I'll create a cookbook of some kind.

The clear attribute of block elements specify whether anything can occur to the left or right or both (either side) of a block element. For example, if a div has 'clear: left' set on it, then no element will be allowed to be left of it. If there is, then the cleared element will be pushed down to the next line.
Spacing is really important and can be hard to remember at first, but it's really intuitive after you learn it:
Margin
+-----Border---------------------------------------+
| Padding |
| |
| Content |

+--------------------------------------------------+
