Headroom.js is a lightweight, pure JavaScript widget designed to manage the visibility of your page's header as you scroll. Created by Nick Williams, Headroom.js allows your page's header to hide when scrolling down to save screen real estate, and then reappear when scrolling back up, which enhances the user experience, especially on mobile devices. This behavior is customizable with CSS transitions, making it a versatile tool for any web developer looking to improve the usability and interactivity of their website designs.
