HTML FORMS

HTML - Forms

HTML Forms are needed when you want to collect some data from the site user. For instance, during user registration information such as name, email address, credit card, etc will be collected. A form will take input from the site visitor and then will post it to a back-end application such as CGI, ASP Script or PHP script etc. The back-end application will perform required processing on the passed data based on defined business logic inside the application. There are various form elements available like text fields, textarea fields, drop-down menus, radio buttons, checkboxes, etc. The HTML form tag is used to create an HTML form and it has following syntax. 

    •       
<!DOCTYPE html>
<html>    
<head >     
<title>Form </title >
</head> 
<body> 
    <form>
        <input type="text">
        <input type="submit"  value="submit">
