Step 1
Create a new folder where you want to store the files for this chapter. I called mine payment-app. Next, add an index.html file with the following content to it.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Payment Form</title>
</head>
<body>
</body>
</html>
