Hier ist ein einfaches Beispiel in Vanilla Javascript.

Du kannst alle Bilder nebeneinander hinter einer Maske positionieren und mit Javascript das Bild scrollen.

<style>
.container {
    width: 300px;
    overflow: hidden;
    position: relative;
}

.track {
    display: flex;
    transition: transform 0.3s ease;
}

.item {
    min-width: 100%;
}

img {
    max-width: 100%;
    height: auto;
}
</style>

<div class="container">
    <div class="track" id="track">
        <div class="item"><img src="1.jpg"></div>
        <div class="item"><img src="2.jpg"></div>
        <div class="item"><img src="3.jpg"></div>
    </div>
</div>

<script>
const track = document.getElementById('track');
let dragging = false;
let startPos = 0;
let currPos = 0;
let prevPos = 0;

track.addEventListener('mousedown', (e) => {
    dragging = true;
    startPos = e.clientX;
    prevPos = currPos;

    document.addEventListener('mousemove', handleMouseMove);
    document.addEventListener('mouseup', handleMouseUp);
});

function handleMouseMove(e) {
    if (dragging) {
        const currentPosition = e.clientX;
        currPos = prevPos + currentPosition - startPos;
        updateCarouselPosition();
    }
}

function handleMouseUp() {
    dragging = false;
    document.removeEventListener('mousemove', handleMouseMove);
    document.removeEventListener('mouseup', handleMouseUp);
}

function updateCarouselPosition() {
    track.style.transform = `translateX(${currPos}px)`;
}
</script>
