@PixelGeek Great info for beginners. I did notice one thing you may want to change for clarity's sake.
You listed the display elements left to right, but in the text below, you've reversed inline and inline-block. I realize there's a tool tip on hover, but some people just start clicking away.
Thanks for the good work!
