No I am sorry to say that I have not heard anything about that.
I am just a little bit disappointed that all that hard work that
looked good for a couple of months is now compromised by the
changes. I am self taught in CSS and HTML and coding (with a lot of
help from Wolfhound) so I am not even sure what I would need to
change to make this work out like it should.
With the custom CSS option, you can put that rule in one place
and then it will be applied to all div's with the "whiteBox" class.
That's much, much easier than pasting it into every single page,
especially when you want to make a change.
As part of adding the new custom CSS feature, we also made some
changes to the underlying HTML markup to hopefully make it easier
to do styling in the future. We standardized some classes, added a
few IDs, and generally tried to make things easier to style.
Unfortunately, this might conflict with existing styling, which is
probably what happened here.
I hate to say it, but the best course of action is to extract
all the styling out of the HTML and put it in the custom CSS
location. It's laborious, but you'll see immediately how the custom
CSS will save loads of work in the future.
If you need more help, just ask on the forums. There are a lot
of people there who are skilled in CSS and can give tips on how to
fix most problems.
