    HTML FORM is used to select different kinds of user input. A form is an area that can contain form elements. Form elements are elements that allow the user to enter information (like text fields, textarea fields, drop-down menus, radio buttons, checkboxes, etc.) in a form.

    • type="text": It specifies a single line text entry field within the form that contains it.
    • type="submit": When the user clicks on the button, the form is submitted.
    • type="reset": When the user clicks on the button, all the fields in the form are reset to their initial values.
