[Typo3] Wrap all content frame

[luca marletta]

Is there the possibility to wrap all content for left column/frame,
for instance?
I mean not in the template because otherwise I have all hard format
(with images for rounded corner box there in every page even if the
content is empty.
I need a solution that wrap all the content of my left column just
before it is rendered.

The optimal solution could me customize a content framing (like:
indent, Frame 1, Frame 2) but where are them in the code? Which way I
can modify them?
