Summary
Forms provide a basic interface for adding interactivity to a Web site. HTML and XHTML support traditional graphical user interface controls such as check boxes, radio buttons, pull-down menus, scrolled lists, multi- and single-line text areas, and buttons. These fields can be used to build a form that can be submitted to a server-side program for processing. While making a rudimentary form isn't terribly difficult, laying out the form often is overlooked. Using tables and improved grouping tags such as <label>, <fieldset>, and <legend> can improve a form dramatically. Accessibility features initially introduced by HTML 4.0, such as accelerator keys and tabbing order specification, also can improve how a form is used. Even browser extensions often frowned upon can improve form use. While next generation forms also are in the works, for now designers should be content with the standard form features offered in HTML and XHTML.
