First, we need an HTML file to contain our animation effects. Create a new file in the code editor and add the following content:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
<div class="glow-effect"></div>
</body>
</html> In the above code, we have introduced a CSS file named styles.css and added the following content in # A div element with the glow-effect class is added to the ##body tag. Our streamer effect will be applied to this div element.
styles.css file to implement our streamer effects. Create a new file in the code editor and add the following content:
.glow-effect {
width: 200px;
height: 200px;
background: linear-gradient(45deg, #ff0000, #00ff00, #0000ff);
animation: glowing 2s infinite;
}
@keyframes glowing {
0% {
box-shadow: 0 0 5px #ff0000, 0 0 20px #ff0000;
}
50% {
box-shadow: 0 0 20px #ff0000, 0 0 40px #ff0000;
}
100% {
box-shadow: 0 0 5px #ff0000, 0 0 20px #ff0000;
}
