Example: The four CSS properties
margin-top: 10; margin-bottom: 9; margin-left: 5; margin-right: 4;can be written as a single property:
margin: 10 4 9 5;Other examples are border and padding. Three suggestions for remembering the order:
- tar ball: is a mnemonic for trbl, the first characters of top, right, bottom, left.
- trouble: an alternative to tar ball, suggested by Josh Feuerstein and Rick Waldron.
- clockwise: means that you enumerate the sides of a rectangle, starting at 12 o’clock, continuing clockwise. Suggested by Franz Graf.
margin: 10 4 9 5; /* trbl */
