                               FORMS IN HTML

                     HTML forms are used to collect information from the site visitors. Different types of forms can be
                     created in HTML like sign up/register, application form, feedback form, query form, etc. The three
                     important components of a form in HTML are: a <FORM> tag, the input controls and buttons.

                     The <FORM> tag is used to define a form in an HTML document. It is placed within the <BODY>
                     tag. While designing and building a form, we use different input elements that allow site visitors
                     to type or select information. These elements can include text fields, radio buttons, checkboxes,

                     etc. All forms must include a Submit button. When the site visitor fills in the information, then,
                     it should be sent to the webserver for processing after the Submit button is clicked.

                     CREATING FORMS
                     The syntax for creating a form in HTML is:

                     <FORM NAME = "Name of the form” ACTION = "Script URL" METHOD = "GET/POST">

                     ...(Input Elements)
                     </FORM>

                       ACTION: This  attribute  specifies  what action  should  be  taken  once  the  SUBMIT  button  is
                       clicked by the user. The Script URL specifies the location where the data collected by the form is
                       submitted. It also produces a response in return.

                       METHOD: This attribute specifies what will happen when the form is submitted. Two values can
                       be assigned to the METHOD attribute, Get and Post.

                       o  Get:  It is the default  value for  the  METHOD attribute.  The  form data  is sent as the URL
                         variable, i.e., it  appends  the  form data  into  the URL.  Get  value should not  be  used  for
                         sensitive information.

                       o  Post: The form data is sent as an HTTP post transaction and form data is not appended to
                         the URL. This value is used for submitting sensitive information.

                     INPUT CONTROLS
                     Input controls are the elements that are used to accept input from the site visitors. All the controls
                     have to be filled in before submitting the form. Now, learn the various types of input controls.

                                                                                       Images, Links and Forms in HTML5  51
