I’ve been in tweak mode for the past few days, getting this blog ready to duplicate for a coming Lockergnome project (based on MultiUser WordPress). In futzing with my CSS, I’ve had to enter values for positioning left and right (literally). You can define the spacing for margin-top, margin-right, margin-bottom, and margin-left separately – or you can define the spacing for all four (or less) in a single margin property. Employing “margin: 10px 3px 3px 10px” is easy. The trouble is, I could never remember which one was for which position! But I didn’t stay in TRBL for long. Top, Right, Bottom, Left – no trouble at all, so long as I can remember to keep myself in TRBL. Mnemonic devices are so nices.
