Syntax
- a b c
- a is followed by b is followed by c, in that order.
- a | b
- either a or b must occur
- a || b
- either a or b or both must occur, in any order
- [a b]
- brackets, used for grouping
- a?
- a is optional
- a*
- a is repeated 0 or more times
- a+
- a is repeated 1 or more times
- a{1,4}
- a is repeated at least once and at most 4 times.
Juxtaposition is stronger than the double bar,
and the double bar is stronger than the bar.
Thus "a b | c || d e" is equivalent to "[ a b ] | [ c || [ d e]]".
Definitions
- Block-level elements
-
an element which has a line break before and after (e.g. <H1>, <P>)
- Replaced element
-
An element which is replaced by content pointed to from the
element. E.g., <IMG>.
Properties
In each definition
- the default value is shown in bold, or given separately
- values apply to all elements unless otherwise stated
