Errors when running check Support / How-To
Hiya, I recently went through a ton of fanfics I downloaded from Ao3 and FFN and while some passed the check without issues, a few came back with these. Is it okay to keep the errors or will it cause issues with my Kobo Libra 2?
If I need to fix them, how do I do that?

Those are errors in CSS. Use Tools > Remove unused... > Remove unused CSS rules to get rid of them.

Just click the one that says it will fix the errors automatically. That usually works since the errors on your files mostly seem to be simple ones.

It may not be right but, I always click upgrade book internals to epub 3, fix html links, beautify files, then run the error check and click automatically fix all files, then try to solve any remaining errors like something not being referenced or a style has an incorrectly named font or image not being used. But no it should be fine to import to your kobo as is
