Fireworks Animation Using Html Css | Firework Fire Animation

Welcome to Code With Random blog. We learn how to create a Fireworks Animation. We use HTML & CSS  for Fireworks Animation. Hope you enjoy our blog so let’s start with a basic HTML structure for the Fireworks Animation.

Html Code 

<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Fireworks Animation</title>
    <link rel="stylesheet" href="style.css">
</head>

<body>
    <div class="firework"></div>
<div class="firework"></div>
<div class="firework"></div>
</body>

</html>

There is all HTML code for the Fireworks Animation. Now, you can see output without CSS, then we write CSS for the Fireworks Animation.
