Extended Cascading Stylesheets
csx - Create, manipulate and convert CSX stylesheets.
CSX is a style language based on CSS 2.1, with two improvements:
- Rules may be nested inside other rules.
- There are no at-rules (like @media or @import).
CSX is also somewhat stricter than CSS (for example, you can’t split a quoted string over more than one line, and comments must be terminated).
See the file README.txt provided with this module for a complete description of the differences between CSS and CSX.
