display: none;
text-align: center;
padding: 123px;
}
.x.active {

.prev,
.next {
position: absolute;
top: 40%;
background-color: #EAFAF1;

right: 10px;
}
</style>
<body>
<div class="x active">
<h1>SLIDE 1</h1>
<p>HELLO</p>
</div>
<div class="x">
<h1>SLIDE 2</h1>
<p>WELCOME</p>
</div>
<div class="x">
<h1>SLIDE 3</h1>
<p>THANK YOU.!</p>
</div>
<button class="prev" onclick="prevSlide()">Previous</button>
<button class="next" onclick="nextSlide()">Next</button>
<script>
let a = 0;
const slides = document.querySelectorAll('.x');
function showSlide(n) {
slides[a].classList.remove('active');
a = (n + slides.length) % slides.length;
slides[a].classList.add('active');
}
function prevSlide() {
showSlide(a - 1);
}
function nextSlide() {
showSlide(a + 1);
}
showSlide(a);
</script>
</body>
</html>
