Forms allow us to prompt a user for input using elements such as radio buttons, checkboxes and selection lists. Data gathered in this manner can then be posted to a server for processing. A form is created by enclosing HTML controls and other elements within <form></form> tags. A page can contain as many forms as required, but they cannot be overlapping or nested (the closing </form> tag of a form must precede the opening tag of any subsequent form).
