<!-- | |
<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. | |
