so I upgraded from 2.1.45 to 2.1.56. So a lot of things are changed. Especially the place where the .css files are located. In the Webinspector there is now a crypic http://(here is a number like a IP adress or so?)/_anki/pages/graphs.css as the source of the .css file. But how can I access the file via the finder app? I searched everywhere but couldn’t find it.
They’re bundled in the app and don’t exist as separate files. If you wish to customize the css, you’ll need to inject replacements into the page using a hook.
Maybe https://ankiweb.net/shared/info/712027367 is something for you.
