width: 100%;
display: block;
}
.carousel-nav {
position: absolute;

}
.carousel-nav button {
margin: 0 10px;

<button onclick="prevSlide()">Prev</button>
<button onclick="nextSlide()">Next</button>
</div>
</div>
<script>
let currentIndex = 0;
const items = document.getElementById('carouselItems').children;
const totalItems = items.length;
function showSlide(index) {
const offset = -index * 100;
document.getElementById('carouselItems').style.transform = `translateX(${offset}%)`;
}
function nextSlide() {
currentIndex = (currentIndex + 1) % totalItems;
showSlide(currentIndex);
}
function prevSlide() {
currentIndex = (currentIndex - 1 + totalItems) % totalItems;
showSlide(currentIndex);
}
// 自动轮播
setInterval(nextSlide, 3000);
