- Version: 0.4
-
- Usage:
- Add a script tag for this script and any stylesets you need to use
- to the page in question, add correct class names to CODE elements,
- define CSS styles for elements. That's it!
-
- Known to work on:
- IE 5.5+ PC
- Firefox/Mozilla PC/Mac
- Opera 7.23 + PC
- Safari 2
-
- Known to degrade gracefully on:
- IE5.0 PC
-
- Note: IE5.0 fails due to the use of lookahead in some stylesets. To avoid script errors
- in older browsers use expressions that use lookahead in string format when defining stylesets.
-
- This script is inspired by star-light by entirely cunning Dean Edwards
- http://dean.edwards.name/star-light/.
