Open Notepad or Adobe Dreamweaver or any other Html editor. I am using Dreamweaver. I am suggest to you, use Notepad for better practise.

Step 2.

Copy the below complete HTML code and paste it in your editor.

  <!DOCTYPE html>
  <html>
  <head>
  <title>Welcome To Registration Form</title>
  </head>

	<body>
	<!-- Main div code -->
	<div id="main">
	<div class="h-tag">
	<h2>Create Your Account</h2>
	</div>
	<!-- create account div -->
	<div class="login">
	<table cellspacing="2" align="center" cellpadding="8" border="0">
	<tr>
	<td align="right">Enter Name :</td>
	<td><input type="text" placeholder="Enter user here" class="tb" /></td>
	</tr>
	<tr>
	<td align="right">Enter Email ID :</td>
	<td><input type="text" placeholder="Enter Email ID here" class="tb" /></td>
	</tr>
	<tr>
	<td align="right">Enter Username :</td>
	<td><input type="text" placeholder="Enter Username here" class="tb" /></td>
	</tr>
	<tr>
	<td align="right">Enter Password :</td>
	<td><input type="password" placeholder="Enter Password here" class="tb" /></td>
	</tr>
	<tr>
	<td align="right">Enter Confirm Password :</td>
	<td><input type="password" placeholder="Enter Password here" class="tb" /></td>
	</tr>
	<tr>
	<td></td>
	<td>
	<input type="reset" value="Clear Form" id="res" class="btn" />
	<input type="submit" value="Create Account" class="btn" onclick="registration()" /></td>
	</tr>
	</table>
	</div>
	<!-- create account box ending here.. -->
	</div>
	<!-- Main div ending here... -->
	</body>
	</html>

Step 3.

Now apply the CSS to all Elements for better presentation. First create CSS <style> .. </style> tag in between <head> .. </head> tag like below.


    <head>
    <style type="text/css">
    
    all css code come here....
    
    </style>
    </head>

Now copy the below CSS code and paste it in between <style> .. </style> tag.


    /* body css for whole page */
    body
    {
	    margin:0px;
	    background-color:#f26724;
	    background-image:url(image/background.jpg);
	    color:#f9fcf5;
	    font-family:Arial, Helvetica, sans-serif;
    }
    
    #main{width:600px; height:auto; overflow:hidden; padding-bottom:20px; margin-left:auto; margin-right:auto; 
    border-radius:5px; padding-left:10px; margin-top:100px; border-top:3px double #f1f1f1; 
    border-bottom:3px double #f1f1f1; padding-top:20px;
    }
    
    #main table{font-family:"Comic Sans MS", cursive;}
    /* css code for textbox */
    #main .tb{height:28px; width:230px; border:1px solid #f26724; color:#fd7838; font-weight:bold; border-left:5px solid #f7f7f7; opacity:0.9;}
    
    #main .tb:focus{height:28px; border:1px solid #f26724; outline:none; border-left:5px solid #f7f7f7;}

    /* css code for button*/
    #main .btn{width:150px; height:32px; outline:none;  color:#f7f7f7; font-weight:bold; border:0px solid #f26724; 
    text-shadow: 0px 0.5px 0.5px #fff; border-radius: 2px; font-weight: 600; color: #f26724; letter-spacing: 1px; 
    font-size:14px; background-color:#f1f1f1; -webkit-transition: 1s; -moz-transition: 1s; transition: 1s;}
  
    #main .btn:hover{background-color:#f26724; outline:none;  border-radius: 2px; color:#f1f1f1; border:1px solid #f1f1f1;
    -webkit-transition: 1s; -moz-transition: 1s; transition: 1s; }
    

Step 4.

Here we will add JavaScript code for validation check. If textbox will blank, password not match, password not in valid form and email id not valid then it will give error message.

Now create JavaScript <script> .. </script> tag in between <head> .. </head> tag like below example.

Example: add JavaScript tag

    
    <head>
    <script>
    
    paste code here..
    
    </script>
    </head>

After that copy the below JavaScript code and paste it in between <script> .. </script> tag.

	
    function registration()
	{

		var name= document.getElementById("t1").value;
		var email= document.getElementById("t2").value;
		var uname= document.getElementById("t3").value;
		var pwd= document.getElementById("t4").value;			
		var cpwd= document.getElementById("t5").value;
		
        //email id expression code
		var pwd_expression = /^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-])/;
		var letters = /^[A-Za-z]+$/;
		var filter = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;

		if(name=='')
		{
			alert('Please enter your name');
		}
		else if(!letters.test(name))
		{
			alert('Name field required only alphabet characters');
		}
		else if(email=='')
		{
			alert('Please enter your user email id');
		}
		else if (!filter.test(email))
		{
			alert('Invalid email');
		}
		else if(uname=='')
		{
			alert('Please enter the user name.');
		}
		else if(!letters.test(uname))
		{
			alert('User name field required only alphabet characters');
		}
		else if(pwd=='')
		{
			alert('Please enter Password');
		}
		else if(cpwd=='')
		{
			alert('Enter Confirm Password');
		}
		else if(!pwd_expression.test(pwd))
		{
			alert ('Upper case, Lower case, Special character and Numeric letter are required in Password filed');
		}
		else if(pwd != cpwd)
		{
			alert ('Password not Matched');
		}
		else if(document.getElementById("t5").value.length < 6)
		{
			alert ('Password minimum length is 6');
		}
		else if(document.getElementById("t5").value.length > 12)
		{
			alert ('Password max length is 12');
		}
		else
		{				                            
               alert('Thank You for Login & You are Redirecting to Campuslife Website');
			   // Redirecting to other page or webste code. 
			   window.location = "http://www.campuslife.co.in"; 
		}
	}
