Step 1. Make a HTML file and define markup, scripting and styling

<html>
<head>
<script type="text/javascript">
function disable()
{
 document.onkeydown = function (e) 
 {
  return false;
 }
}
function enable()
{
 document.onkeydown = function (e) 
 {
  return true;
 }
}
</script>
<style>
body
{
 margin:0 auto;
 padding:0px;
 text-align:center;
 width:100%;
 font-family: "Myriad Pro","Helvetica Neue",Helvetica,Arial,Sans-Serif;
 background-color:#21618C;
}
#wrapper
{
 margin:0 auto;
 padding:0px;
 text-align:center;
 width:995px;
}
#wrapper h1
{
 margin-top:50px;
 font-size:45px;
 color:#FDF2E9;
}
#wrapper h1 p
{
 font-size:18px;
}
#text_div textarea
{
 width:350px;
 height:100px;
 padding:10px;
}
#text_div input[type="button"]
{
 width:100px;
 height:35px;
 margin-top:5px;
 background:none;
 border:1px solid white;
 color:white;
 font-weight:bold;
}
</style>
</head>
<body>
<div id="wrapper">

<div id="text_div">
<textarea placeholder="Enter Text"></textarea>
<input type="button" value="DISABLE" onclick="disable();">
<input type="button" value="ENABLE" onclick="enable();">
</div>

</div>
</body>
</html>

In this step we create a textarea to test keyboard before and after disabling and enabling. We create two buttons to disable and enable keyboard and we also create two functions disable() and enable() and use onkeydown() function to track keypress and use false and true respectively.
