    HTML forms are 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", which specifies a single line text entry field within the form that contains it.
    • type="submit", which submits the form when a user clicks the button.
    • type="reset", which re-sets all the fields in the form to their initial values when a user clicks the button.
