Staying out of TRouBLe with CSS

Staying out of TRouBLe with CSS: "Trick to Remembering Shorthand Orders for margin, padding, and border

Many CSS properties define the top right bottom and left sides of an element. In order to use the shorthand versions of these properties (for example: margin instead of margin-top, padding instead of padding-left), you need to have your numbers in a very specific order.

That order is:
top
right
bottom
left

An easy way to remember this is to think 'TRouBLe'. If you don't use this order you'll get in 'TRouBLe'."
