An idea I never tried on ePub's: use "display:table;" in place of "float:left/right;".
An explanation can be find here :

Compatibility with browser :

I use the "display:table;" here

- footer : "A propos", "Liens utiles" and "Oh!Bises" are displayed in table.
- That's a copy of another site which explain the capacities of html5 (I can't retrieve the original in english, sorry)
