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

HTML code

 <!DOCTYPE html>  
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Custom Countdown</title>
<link rel="icon" type="image/png" href="favicon.png" />
<link rel="stylesheet" href="style.css" />
</head>
<body>
<!-- Video Background -->
<video class="video-background" loop muted autoplay>
<source src="time.mp4" />
</video>
<div class="video-overlay"></div>
<!-- Container -->
<div class="container">
<!-- Input -->
<div class="input-container" id="input-container">
<h1>Create a Custom Countdown</h1>
<form class="form" id="countdownForm">
<label for="title">Title</label>
<input
type="text"
id="title"
placeholder="What are you counting down to?"
/>
<label for="date-picker">Select a Date</label>
<input type="date" id="date-picker" />
<button type="submit">Submit</button>
</form>
</div>
<!-- Countdown -->
<div class="countdown" id="countdown" hidden>
<h1 id="countdown-title">Countdown Title Here</h1>
<ul>
<li><span></span> Days</li>
<li><span></span> Hours</li>
<li><span></span> Minutes</li>
<li><span></span> Seconds</li>
</ul>
<button id="countdown-button">Reset</button>
</div>
<!-- Countdown Completed -->
<div class="complete" id="complete" hidden>
<h1 class="complete-title">Countdown Complete!</h1>
<h1 id="complete-info"></h1>
<button id="complete-button">New Countdown</button>
</div>
</div>
<!-- Script -->
<script src="script.js"></script>
</body>
</html>

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