let slider = document.querySelector('.slider');
let sliderWidth;
let imageWidth;
let current = 0;
let target = 0;
let ease = .05;
let images = [...document.querySelectorAll('.img')];

images.forEach((img, idx) => {
    img.style.backgroundImage = `url(https://www.industrialempathy.com/img/remote/ZiClJf-1920w.jpg)`
})


    function lerp(start, end, t) {
        return start * (1 - t) + end * t;
    }

    function setTransform(el, transform) {
        el.style.transform = transform;
    }

    function init() {
        sliderWidth = slider.getBoundingClientRect().width;
        imageWidth = sliderWidth / images.length;
        document.body.style.height = `${sliderWidth - (window.innerWidth - window.innerHeight)}px`
    }

    function animate() {
        current = parseFloat(lerp(current, target, ease)).toFixed(2);
        target = window.scrollY;
        setTransform(slider, `translateY(-${current}px)`)
        animatedImage();
        requestAnimationFrame(animate);
    }

    function animatedImage() {
        let ratio = current / imageWidth;
        let RatioValue;

        images.forEach((image) => {
            RatioValue = ratio - (0.2);
            setTransform(image, `translateX(-${RatioValue * 20}px)`)

        })
    }


    init();

    animate();
