# Night PDF

This repository hosts the source code for the Night PDF extension, a simple browser extension that applies a dark theme to your PDF viewer.



  



This extension is a fork of [PDF Dark Theme][pdf-dark-theme-link] by [Chris Straka][chris-straka-link] with some extra functionality, specifically:

- Toggling between multiple dark themes by clicking the extension icon

- Works on local and online PDFs

## Using and Customising the Extension

To use the extension, [download and install the extension](https://dev.to/ben/how-to-install-chrome-extensions-manually-from-github-1612 "Learn how to download and install extensions from GitHub.")

using Developer Mode (this extension is not available via the Chrome Web Store or other extension websites). Refresh any open tabs after installing the extension.

To customise the dark themes, simply modify the [colours in the `backgroundColours` array](https://github.com/anipalur/night-pdf/blob/main/content-script.js#L10 "View the colours in the backgroundColours array.") in content-script.js.
