<shadow> = inset? && <length>{2,4} && <color>?
|
|
|
|
A comma-separated pair of numbers in curly braces {A,B}
|
|
indicates that the preceding type, word, or group occurs
|
|
at least A and at most B times.
|
|
|
|
A question mark (?) indicates that the preceding type,
|
|
word, or group is optional (occurs zero or one times).
|
|
|
|
The components of each <shadow> are interpreted as follows:
|
|
|
|
1st <length>
|
|
Specifies the horizontal offset
|
|
of the shadow. A positive value draws a shadow that is offset to the right of the box, a negative length to the left.
|
|
2nd <length>
|
|
Specifies the vertical offset
|
|
of the shadow. A positive value offsets the shadow down, a negative one up.
|
|
4th <length>
|
|
Specifies the spread distance. Positive values cause the shadow to expand in all directions by the specified radius. Negative values cause the shadow to contract.
