CSS:

Import dist/style.css to your CSS. It's few lines of code. You can alternatively copy paste it and adjust things like z-index to your needs.

JavaScript:

import { hidingHeader } from 'hiding-header'

const container = document.querySelector('#hidingHeader')
hidingHeader(container)

import { hidingHeader } from 'hiding-header'

const container = document.querySelector('#hidingHeader')
const instance = hidingHeader(container, {
	heightPropertyName: '--hidingHeader-height',
	boundsHeightPropertyName: '--hidingHeader-bounds-height',
	animationOffsetPropertyName: '--hidingHeader-animation-offset',
	snap: true, // Reveal or hide header if user stops scrolling in middle
	onHeightChange: (height: number) => {}, // When content height changes
	onVisibleHeightChange: (height: number) => {}, // When part of header is revealed
	onHomeChange: (isHome: boolean) => {}, // When returns to home
})

instance.pause() // Pauses recalculations of sticky boundaries on scroll
instance.isPaused() // Check if paused
instance.run() // Reactivates
instance.destroy() // Removes all internal event listeners

instance.reveal() // Reveals header if hidden
instance.hide() // Hides header if visible

instance.getHeight() // Returns content height in pixels
instance.getVisibleHeight() // Returns height of visible content area in pixels

instance.isHome() // Returns true if element is at initial position, e.g. user has not yet scrolled
