Hello.
I find a Addon Manager in C3,
but i cannot find a CSS Addon to C3...
I try to convert my project from C2 to C3 (using one file),
and there is a problem with css.
Can you help me?
(sorry for post a second topic about this problem).
Is this a user-made addon for C2?
If so, then it will need to be converted to C3, usually by the author.
Please try to clarify what it is you are trying to do.
