Still find things that make you go "how do they do that?" Have no fear!
See, the pages you see in your browser are actually coded in plain text. You can look at the code and see for yourself exactly how somebody did the cool effect that they did.
Right-click on the page (use your alternate mouse button) and you'll get a menu. Click "View Source..." (or go to the View menu and pick Source...")
You'll get a lot of irrelevant gobbeldygook, but somewhere in there is the code for that neat trick you want to copy. The easiest way to home in on it is to do a "Find..." (I think it's on the Edit menu in Notepad) and search for the visible part of the text that the neat trick uses.
