ReadiumCSS Reset/Unset

[JayPanoz]

I'm submitting a topic for discussion, as requested by @danielweck during the monthly call yesterday.

Short description of the issue/suggestion:

There might be a use case for a ReadiumCSS reset/unset, in the form of a user switch disabling ReadiumCSS styles (esp. the ones in the before stylesheet, that apply unless they are overridden by authors’).

Of course developers might just reload EPUB contents w/o ReadiumCSS to achieve such an effect, but some very basic stylesheet and/or ability to unset styles more finely may help as well. This issue should help clarify what the best option would be.
