However, this doesn't make any sense to me either as I've no reason to believe there's anything wrong with cssutils ( which I use every day for css tweaking) and !important is valid css.
If you want to troubleshoot it, have you tried temporarily disabling kobo_extra.css and adding your font rules manually - also leaving the !important occurrences as-is? Does the Kobo still reject the whole css file?
For myself I've side-stepped the problem by auto-removing all occurrences of !important whenever I tweak css because I can see no good reason for a well-constructed book to need them in the internal css. |
I have certainly seen some differences in the book rendering in my experimentation between CSS being added manually and auto-applied from kobo_extra.css, but that made no sense either
I do not recall if
!important was involved in that particular setup, and I think the only issue was whether it would actually use the monospace font or not, the remainder of the CSS worked fine.
I ended up doing the same thing you do — I strip out all
!important from the CSS. In all cases I've seen so far it was in the CSS I had absolutely no interest in to begin with.
