## Description

This extension was created to introduce dark mode to workspace/educational websites that do not have a native dark mode. 

<i>Flashbang</i> uses CSS stylesheets which are applied to the following websites:
     - Google Drive
     - Google Docs Editors Suite (Google Docs, Google Slides, etc.)
     - D2L Brightspace (see Github link for more info)

To toggle off the extension, you must navigate to your browser's extension manager and manually disable it.

<b>IMPORTANT NOTE</b>: Quizzes in D2L will have their color inverted, due to how the color scheme is programmed. It is recommended that you temporarily disable this extension whenever taking quizzes on D2L.
