Overview

A zero-FOUC dark theme for Blackboard Ultra. Toggle via the popup.

Blackboard Ultra has no dark mode. My extension Darkboard fixes that. You install it once and every page on your school's Blackboard automatically switches to a clean, eye-friendly dark theme that gets rid of the eyestrain of using BlackBoard in the evenings. Built by a Computer Science student at Iona University for the Iona community. Lightweight, open-source, and actively maintained. Found a bug or want to see the code? Open an issue on the GitHub repo, the link is in the extension popup.
