css documentation

i have downloaded activewidgets-grid-1.0-gpl.zip. where can i find the documentation for the styles from grid.css? is there a place where i can see what is the purpose of each css / where is it used? is this avialable in the commercial version?
thank you

No, it is currently not available. Alex has said that the 2.0 release should have better docs but I don't know if this will be covered in detail like you are requesting. Perhaps you could play around with the file, make changes and document what each does and submit it for consideration in 2.0?
