Hello, guys in this tutorial we will create an animated snake border using HTML & CSS.

First, we need to create two files index.html and style.css then we need to do code for it.

Snake border animation Step:1

Add below code inside index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <title>Rotating Border Animation</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta http-equiv="X-UA-Compatible" content="ie=edge" />
    <link rel="stylesheet" href="style.css" />
  </head>
  <body>
    <div class="anim-border">
      <img src="rahul.jpg">
    </div>
  </body>
</html>
