Parallax Demo

This demo below is a basic example of creating a parallax background image using Tailwind CSS. See it in action at use-page-offset.netlify.app

import { usePageOffset } from 'use-page-offset'

const App = () => {
    const offset = usePageOffset()
    const parallaxSpeed = 3
    return (
        <div className="relative py-64 bg-red-500 overflow-hidden">
            <div
                className="absolute top-0 left-0 w-full h-full object-cover z-10"
                style={{
                    transform: 'translate(0px, ${offset / parallaxSpeed}px)',
                    backgroundImage: 'url("https://via.placeholder.com/1200x400")',
                }}
            ></div>
            <div className="text-center relative z-20">
                <h1 className="text-5xl font-bold pb-4 text-blueGray-800">Text Overlay</h1>
            </div>
        </div>
    )
}

export default App

How does this work?

Use Page Offset is a super simple react hook that tracks the pageYOffset of the browser window so you can easily build in effects like parallax & scroll effects.
