How to create Html Forms


Hello guys, morning, welcome you all to this section of my tutorial, in my last tutorial i talked about HTML fonts and how to style your web pages with various fonts and also how to change font sizes. So today lets talk about how to creat various HTML forms.
 HTML Forms are required, when you want to collect some data from the site's visitors. For example, during user registration you would like to like to collect some informations such as name, email address, credit cared, date of birth and so on.
A form will take the inputed datas from the site's visitors and then will post it to a back end application such as ASP Script, CGI 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 a HTML form and it the following syntax:

<form action="script url" method="GET l POST">
       form content 
</form>

Form Attributes
Apart from common attributes, following is the list of the most frequently used form attributes:

Now that we have talked about form attributes, let us move on to the next which is HTML form controls.

Text Input Controls
There are three types of text input used on forms:
Single-line text input control - This control is used for items that require only one line of the user's input, such as search boxes or names. They are created using HTML <input> tag.
