Basic formatting tags not working because of base CSS redefinition

[taldcroft]

The base CSS for astropy.org starts with a definition that basically removes useful HTML formatting tags like <it>, <sup>, <strong> etc. I understand wanting to have a highly uniform and simplified look, but it seems like this is going too far. In particular now I want to use <sup> and it isn't possible. This is something that a SO post specifically discouraged from doing with pure CSS.

Would there be a problem with liberating a few of these?
