  description

  Darkboard is a high-performance, deeply integrated dark theme extension designed specifically for the modern Blackboard Ultra interface. Whether you’re pulling an all-nighter on a coding project or checking grades at 2 AM, Darkboard replaces blinding white backgrounds with a sleek, high-contrast interface that's easy on the eyes and built for focus.
  
  Darkboard was built by a Computer Science student at Iona University to solve a real-world problem for the campus community. It’s open-source, lightweight, and designed to make your academic workflow smoother and allow for less eyestrain during late night study sessions.
  
  Currently, Darkboard is designed for the Iona University community. In the future I plan to make this accessible to all students at Universities that use Blackboard.

  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.
