Midnight.js
Switch your nav's design on the fly
A jQuery plugin that switches between multiple header designs as you scroll, so you always have a header that looks great with the content below it. Create your fixed nav (or header) as you typically would. Create your fixed nav (or header) as you typically would. You can use whatever markup suits you, just make sure the header works well with position:fixed. After that, take any sections of your page that need a different nav and add data-midnight="your-class" to it, where .your-class is the class you are going to use to style that header. If you don't use the property or just leave it blank, the .default class will be used for that section. You can style it in your CSS using the class .midnightHeader.your-class. Use whatever CSS or markup you like for each one. They will be switched automatically when necessary. To make everything work, just load midnight (and jQuery) and initialize it. We take care of the rest. -

Mermaid.js to SVG Converter
Visualize the diagrams of your projects
While coding with AI assist, I noticed bigger projects need something more rigid as context so the AI coder doesn't stray away when I try to add new features. You know, to keeps its memory fresh and not change the stuff that already works. The trick is to ask the AI to write a diagram in Mermaid.js format that solidifies the structure of the project and then use that as context to keep the AI reminded at all times what the project is as a whole. This will prevent it from changing things its not supposed to change. This standalone offline web app will convert that mermaid.js code into a visual SVG image so that YOU as a human will be able to understand what the AI think about the structure of your projects so you can see it and fix any misconceptions until the diagram is correct for your project. (Source code is included in the html itself. Open it in a web browser to use.) -

Definitely interesting, and if you're developing mostly web content and not applications this is particularly useful. It is a web dev build tool/scaffold that does not depend on any framework. You can import any external libraries/frameworks or native ES Modules for production. The generated core file in the dist directory can be used separately in any website. Support JS, HTML, and SASS component library automatically packaged. It is used to develop the full-static website (HTML templates or for dynamic language integration). The demo depends on jQuery (you can completely rewrite the script if needed). And dist DOES NOT bundle any third-party script and style library, all libraries are loaded externally in the HTML file.
