    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>

                      The description of FORMS syntax are as follows:
                         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.
                            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.

                            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.

                      Text Input Controls
                      There are three types of text input controls used on forms: Single-line text input control, Password
                      input control and Multi-line text input control.
                      Single-line text input control

                      This control is used to enter single-line inputs. It is used as a search box or name. The two attributes
                      associated with single-line text input controls are: SIZE and MAXLENGTH. The SIZE attribute
                      defines the size of the text box and MAXLENGTH defines the number of characters the textbox
                      can hold.
