I'm trying to add some HTML to my notes using Bootstrap CSS. If I copy all the CSS into a style-tag of the note, it works, however I'd like to know if there's a way to make a single CSS file, which every note refers to and uses for CSS.
It looks like that's what I need, however unfortunately copying the CSS that worked in the tags of the note itself into the userstyle.css doesn't seem to have any effect on the note in the end... I quit and restarted Joplin several times, no change.
