Hello guys in this tutorial we will create animated hover effect using HTML & CSS
First we need to create two files index.html and style.css then we need to do code for it.
Step:1
Add below code inside index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Hover Glow Effect</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta https-equiv="X-UA-Compatible" content="ie=edge" />
<link rel="stylesheet" href="style.css" />
<link href="https://fonts.googleapis.com/css2?family=IBM+Plex+Sans&display=swap" rel="stylesheet">
</head>
<body>
<div class="btn-outer">
<button class="glow-hover">Hover Me</button>
</div>
</body>
</html>Step:2
Then we need to add code for style.css which code i provide in below screen.
* {
padding: 0;
margin: 0;
font-family: 'IBM Plex Sans', sans-serif;
}
body {
display: flex;
align-items: center;
justify-content: center;
height: 100vh;
background: #000;
}
.glow-hover {
width: 200px;
height: 50px;
border: 0;

color: #fff;
background: #444;
font-size: 15px;
text-transform: uppercase;

}
.glow-hover:before {

background: linear-gradient(45deg, #ff0000, #ff7300,
#fffb00, #48ff00, #00ff45,
#002bff, #7a00ff, #ff00c8, #ff0000);
background-size: 400%;

filter: blur(5px);
width: 100%;
height: 100%;
opacity: 0;
