.carousel {
width: 80%;
margin: 0 auto;
overflow: hidden;
position: relative;
}
.carousel-inner {
display: flex;
transition: transform 0.5s ease-in-out;
}
.carousel-item {
min-width: 100%;
height: 300px;

display: flex;

}
.arrow {
position: absolute;
top: 50%;
transform: translateY(-50%);
cursor: pointer;
font-size: 24px;
color: #333;
}
.left-arrow {
left: 10px;

.right-arrow {
right: 10px;
}
</style>

<body>
<div class="carousel" id="carousel">
<div class="arrow left-arrow" onclick="prevSlide()">❮</div>
<div class="carousel-inner" id="carouselInner">
<div class="carousel-item">1</div>
<div class="carousel-item">2</div>
<div class="carousel-item">3</div>
</div>
<div class="arrow right-arrow" onclick="nextSlide()">❯</div>
</div>
<script>
let currentIndex = 0;
const items = document.querySelectorAll('.carousel-item');
const totalItems = items.length;
function showSlide(index) {
const offset = -index * 100;

}
function nextSlide() {

if (currentIndex >= totalItems) {
currentIndex = 0;
}
showSlide(currentIndex);
}
function prevSlide() {

}
showSlide(currentIndex);
