GitHub-Dark is a browser extension theme and collection of user style sheets designed to provide a comprehensive dark mode aesthetic for the GitHub interface. It functions by injecting custom style rules directly into the browser to override default website colors, fonts, and layout properties, aiming to improve visual comfort and readability during extended use.
The project distinguishes itself through its focus on deep integration and visual consistency. It includes specialized support for syntax highlighting across various programming languages and notebook environments, ensuring that code blocks remain legible within the dark theme. Furthermore, it maintains compatibility with third-party browser extensions and developer tools, applying normalization rules to ensure that external interface components adhere to the unified dark aesthetic.
Beyond its core theming capabilities, the project provides options for users to customize specific interface elements such as sidebar behavior, tab sizes, and border styles. The codebase is maintained through automated build and linting pipelines that enforce strict style standards and manage version releases to ensure consistent performance across different browser environments.
