HTML Controls
The HTML controls are a set of older user interface (UI) controls that are supported by all
Web browsers and conform closely to the early HTML standards developed for managing
UI elements on a typical Web page. They include Button, Text, and Checkbox—useful basic
controls for managing information on a Web page that can be represented entirely with HTML
code. Indeed, you might recognize these controls if you’ve coded in HTML before. However,
although they’re easy to use and have the advantage of being a “common denominator”
for Web browsers, they’re limited by the fact that they have no ability to maintain their own
state. (In other words, the data that they contain will be lost between views of a Web page .)
