/* CSS for Paged.js interface – v0.2 */

/*
DONE:
* fixed spread mode so it's exactly aligned to pagewidth*2 minus the bleed
* rules always on top of everything (for the moment same z-index than the page)
* preview mode that hides all the rules

TODO:
* show margin boxes only when superior to 0 otherwise it overlays the stroke of pagebox!!
* centered zoom (not top left ?)
* position fixed for interface directly in css (use iframe!)
* correction of bug of 1mm added to body.spread .pagedjs_pages
* margin-bottom on last page does not work
