To add Crackers Animation Effect in the HTML Page, you have to add JavaScript to your HTML page which I have mentioned in the below details and its source code has also been given to you so that you can add Crackers Animation Effect to your HTML page.

Firecrackers Effects
Step1:- Create index.html File.
Example:-
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!--this code comes from: httsp://myprograming.com/ -->

Firecrackers Effects
</title>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<canvas id="canvas">Well Come 2022</canvas>
<h1 id="message">By By 2021!</h1>
<script src="demo.js"></script>
</body>
</html>Step2:- Create style.css File.
Example:-
/*basic styles for black background and crosshair cursor*/
body{
background: #630300;
margin: 0;
font-size: 16px;
font-family: Verdana;
}
h1{
pointer-events: none;
font-size: 72px;
background: -webkit-linear-gradient(gold, #333);
-webkit-background-clip: text;
-webkit-text-fill-color: transparent;
}
#message{
width: 100%;
font-size: 2em;
color: white;
text-align: center;
position: absolute;
top:20px;
left: 0;
}
canvas{
cursor: crosshair;
display: block;
}
#canvas{
font-size: 72px;
background: -webkit-linear-gradient(blue,yellow);
-webkit-background-clip: text;
-webkit-text-fill-color: transparent;
}Step3:- Create demo.js File.
Example:-
