To use an HTML button as a link, you have to add some JavaScript code.
JavaScript allows you to specify what happens at certain events, such as a click of a button:
<button onclick="document.location='index.html'">Button Link</button>
<!DOCTYPE html>
<html>
<head>
<title>Button as a Links</title>
</head>
<body>
<h2>Button as a Links</h2>
<button onclick="document.location='/index.html'">Button Link</button>
</body>
</html>
