Welcome🎉 to Code With Random blog. In this blog, we learn that how we create a Reverse countdown. We use HTML, Css, and javascript for this Reverse countdown. Hope you enjoy our blog so let’s start with a basic HTML structure for a Reverse countdown.

HTML code

<div class="number"></div>

There is all HTML code for the Reverse countdown. Now, you can see output without CSS, then we write css & javascript for Reverse countdown.

 :root {  
--background-color: #0e1538;
--text-color: #fff;
--font: sans-serif;
* {
margin: 0;
padding: 0;
body {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
background-color: var(--background-color);
font-family: var(--font);
/* main Card */
.card {
width: 200px;
height: 275px;
position: relative;
user-select: none;
cursor: pointer;
transition: 0.3s ease-in-out;
/* Linear Background by using ::before */
.card::before {
content: "";
position: absolute;
top: -4px;
left: -4px;
bottom: -4px;
right: -4px;
transform: skew(2deg, 4deg);
background: linear-gradient(315deg, #00ccff, #0e1538, #d400d4);
/* countdown number */
.card > .number {
width: 100%;
height: 100%;
position: absolute;
z-index: 10;
font-size: 8em;
display: grid;
place-items: center;
background-color: var(--background-color);
color: var(--text-color);
.card:hover {
transform: scale(1.1);
box-shadow: 0 0 200px rgba(225, 225, 225, 0.3);
transform: rotate(720deg);

Javascript code 

 var number = document.querySelector(".number");  
var count = 20;
// Countdown Interval which runs on every 1s
var countdownInterval = setInterval(() => {
// if count is less than or equal to 1 then clear the Interval
count <= 1 && clearInterval(countdownInterval);
number.textContent = count <= 10 ? `0${--count}` : `${--count}`;
}, 1000);
