Welcome🎉 to Code With Random blog. This blog teaches us how we create a Javascript Digital Clock. We use HTML, Css, and javascript for the Javascript Digital Clock. I hope you enjoy our blog so let’s start with a basic HTML structure for the Javascript Digital Clock.


<html lang="en">
    <meta charset="UTF-8">

    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Javascript Digital Clock</title>
<link rel="stylesheet" href="style.css">

      <span> hover over clock </span>
      <script src="app.js"></script>
