Debugging Apple Books

Notes on debugging Apple Books

Issue #86 (links are hardly visible in Night mode) sparked a search on the internet. The main result:

• the links were all internal links
• the links were marked as 'visited'
• the epub3.css theme colored the visited links dark grey
• external links somehow don't get the 'visited' attribute

Apple Books alters the CSS of the ePub by adding an indication which color mode is used and sets the colors accordingly. Info here: https://stackoverflow.com/questions/14305164/any-way-to-detect-if-dark-theme-is-active-in-ibooks-from-within-epub

All colors are described here: https://gist.github.com/adaptivegarage/aef95223fab9a39db45f
