Hi Jake,

As far as I know, the changes in css are derived by the incorporation of 
the less machinery to get the final css.
The changes were done in the general IPython css styling, and nbconvert 
is just reading the new style contained in style.min.css.
Probably Mathias can go deeper in the explanation because he PRed the 
changes involving less.

You can always get the old style sheet from previous versions of 
IPython, make an old_ipython.css file and include it in your head 
instead of the new styling.
This is the way I used to do it in my plugin for Nikola, although I am 
migrating to the new styling very soon.

Hope it helps.
