Ciao @Mohammad
I wanted to come back to this thread and make a wider comment.
You are absolutely right that TW is excellent for CSS use. There are numerous ways to use CSS in TW.
I know no other software that is so flexible on CSS application!
What is my point?
Well I think the visual design side of TW is somewhat underdeveloped.
That is likely because so far there have not been that many new designs that were documented???
I think it could be very interesting to see more examples of radical use of CSS in TW.
That is not for @jeremyruston per se to document, rather just someone good at CSS design and familiar with TW.
One of the interesting things in TW is it is inherently recursive … i.e. we can make wikis that show how those wikis make themselves.
Clearly it would be possible to create a special TW for showing how to optimise use of CSS with it.
Just a comment
