Impeccable also includes deterministic anti-pattern detection through a CLI and browser extension without requiring an API key.

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. -

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. -

ScrollTrigger
Let your page react to scroll changes
The most basic usage of ScrollTrigger is to trigger classes based on the current scroll position. E.g. when an element enters the viewport, fade it in. You can add custom offsets per element, or set offsets on the viewport (e.g. always trigger after the element reaches 20% of the viewport) When using the callbacks ScrollTrigger becomes really powerful. You can run custom code when an element enters/becomes visible, and even return Promises to halt the trigger if the callback fails. This makes lazy loading images very easy. The easiest way to start is to create a new instance and add some triggers to it, with all default values. This will toggle the 'visible' class when the element comes into the viewport and toggles the 'invisible' class when it scrolls out of the viewport. Adding callbacks / different classes can be done globally, this becomes the default for all triggers you add, or you can specify custom configuration when adding a trigger. -
