Also CSS related, when doing margin/padding I use "TRouBLe" to remember:

    margin: (T R B L)

My one is visualising a clock face, 12, 3, 6, 9

Thats a nice example showing that mnemonics need not be logical to have value (if you asked people to order the numbers on a clock face, I think the vast majority would have them as 3, 6, 9, 12)

Do you have one for border-radius? Because I still can't remember the order of those..

That's the one I use as well.

Although I can never remember the 3 parameter verision

margin: (T R&L B)
