## What it is
Midnight.js is a jQuery plugin that switches between multiple fixed header/nav designs as the user scrolls, based on data attributes on page sections. It automatically creates and swaps styled header variants so the nav always complements the content beneath it.

## Use cases
- switch nav design on scroll
- make fixed header change color per section
- scroll-aware header styling
- swap logo style as user scrolls past dark sections
- multiple header designs for one page

## When to choose
- you use jQuery and want a fixed header that adapts to section backgrounds
- you need per-section nav styling with minimal JavaScript

## When to avoid
- you don't use jQuery
- you need a modern framework (React/Vue) solution
- the project needs active maintenance or new features

- maturity: maintenance
