Shadow Effect
The shadow font effect renders a coloured copy of text with an offset, giving the effect of a shadow.
The effect has the following properties:
offset-x
| Value: | <number> | 
| Initial: | 0 | 
| Percentages: | N/A | 
offset-y
| Value: | <number> | 
| Initial: | 0 | 
| Percentages: | N/A | 
These properties define the offset, in pixels, between the source text and the shadow.

A shorthand property for setting offset-x and offset-y.
