Custom CSS and JS
Custom CSS Plugin for Visual Studio Code. Based on vscode-icon
Custom CSS and JS is a Visual Studio Code extension that allows users to inject custom CSS and JavaScript into the editor interface, enabling deep visual and behavioral customization beyond what standard themes provide. The tool works by modifying VS Code’s internal styling system, allowing developers to override UI elements such as fonts, colors, spacing, and layout with their own stylesheets. This makes it possible to create highly personalized development environments tailored to individual preferences or workflows. In addition to aesthetic changes, users can also inject JavaScript to modify certain UI behaviors, effectively extending the editor’s functionality in unconventional ways. The extension is often used to implement custom themes, improve readability, or experiment with alternative interface designs. However, because it alters internal files, it may require reapplying changes after updates and can raise stability considerations. -

Gloria
Gloria is a static website generator, based on NodeJS
V2 is deprecating lots of old functions, make sure to read the migrating docs. We're also slowly moving into typescript, and while I think it should work very well for your projects, legally I need to remind you that this is a satire of other projects. It currently supports having a content management system using MD files and tailwind CSS, with some bugs, but the main functionality and philosophy have been accomplished. This project aims to be a substitute for Jekyll, to help you create static websites without depending on Ruby. Because of its ease of use, extensibility, and support for md files, is also great for creating websites out of documentation that lives in a source code. -

Markdown documents are automatically rendered into WeChat graphics and text in real-time, so you no longer have to worry about the typesetting of WeChat articles! As long as you know the basic Markdown syntax, you can make a simple and beautiful WeChat graphic. Chrome browser is recommended for best results. In addition, for domestic (China) friends, accessing Gitee Pages will be relatively faster. The existing open-source WeChat Markdown editor has complicated styles and does not meet my personal aesthetic needs. When I use them for article typesetting, I often have to make some changes myself, which is time-consuming and labor-intensive, so I did secondary development. -

nightTab
A neutral new tab page accented with a chosen colour
A neutral new tab page accented with a chosen color. Customize the layout, style, background and bookmarks with nightTab. Make the browser start page dark (or light, or anything in between). Do not access user information. This means nightTab will not request browser permissions. Aim to make everything on the user interface, within reason, customizable. Aim to make the user experience easy while supporting the above. Keep nightTab open source. Sharing the look and feel of one Bookmark to another can be achieved when editing a single Bookmark. The Bookmark edit modal has three options to copy settings to other Bookmarks. These checkboxes can be found at the bottom of the Visual & Name, Layout and Theme tab. Development and testing is only conducted on Chrome and Firefox. The performance and reliability of nightTab on other browsers is out of the scope of this project. -

Chalk
Terminal string styling done right
Chalk 5 is ESM. If you want to use Chalk with TypeScript or a build tool, you will probably want to use Chalk 4 for now. Chalk comes with an easy to use composable API where you just chain and nest the styles you want. Chain styles and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that chalk.red.yellow.green is equivalent to chalk.green. Color support is automatically detected, but you can override it by setting the level property. You should however only do this in your own code as it applies globally to all Chalk consumers. Detect whether the terminal supports color. Used internally and handled for you, but exposed for convenience. chalkStderr contains a separate instance configured with color support detected for stderr stream instead of stdout. Override rules from supportsColor apply to this too. supportsColorStderr is exposed for convenience. -

GitHub Dark
Dark GitHub style
GitHub-Dark is a userstyle that transforms GitHub’s interface into a coherent dark theme, covering repositories, issues, pull requests, gists, and profile pages. Distributed as a CSS stylesheet intended for the Stylus browser extension, it applies a comprehensive palette, rebalances contrast, and refines syntax colors for code views to ensure readability in low-light settings. The project goes beyond simple inversion by thoughtfully adjusting backgrounds, borders, badges, and diff highlights so the UI feels native rather than “flipped.” It includes targeted fixes for edge cases across GitHub’s many subpages, aiming for consistency while preserving the information hierarchy of the original design. Users can apply the theme selectively, override variables, or combine it with other userstyles to fit personal preference. Even with GitHub’s own theme options, GitHub-Dark remains a carefully tuned alternative for people who want a specific aesthetic or more granular control. -
