[texhax] Mathematics Textbook (class or style)

[Victor Ivrii]

Mathematics junior undergraduate/high-school textbooks look rather
different from
the `normal' mathematical monographs (especially colorboxed theorems). While
it is rather easy to do the same in frames of standard article or book
class, I wonder
if there are some special classes or styles for this.

Actually some beamer themes do the same.

Thank you in advance
