| <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. | |
