In reading mode, I would like to style links to my Zotero database (which uses urls like zotero://select/library/items/PI6IBH2C) differently from other external links. In a pure html environment I’d do something like this: a[href^="zotero://"] {} (to select links whose target begins with “zotero://”), but I haven’t been able to figure out how to do that selection in Obsidian.
Things I have tried
I’ve got as far as using the .external-link selector in a css snippet to customize the styling of all external links, but I haven’t figured out how to select based on the target url.
