1.3.1 Element Behaviors and HTML Components

Quirks Mode, IE7 Mode, IE8 Mode, IE9 Mode, and IE10 Mode (All Versions)

Element behaviors allow a developer to define custom elements that can be used in the same way as normal HTML elements in a webpage. Because element behaviors are encapsulated components, they can add functionality to a webpage while improving the reusability and organization of content, script, and style elements.

Element behaviors are synchronously attached to elements through special style sheet rules, or an IMPORT processing instruction such as the following:

 <HTML xmlns:games>
 <HEAD>
 <?IMPORT namespace="games" implementation="checkers.htc" ?>
 </HEAD>
 <BODY>
 <games:checkers />
 </BODY>
 </HTML>

Element behaviors, which are used to define custom elements, are also called HTML Components (HTC). The implementation of the HTC is encapsulated in an .htc file.

The following elements and attributes are used to define the public interface and event model of an HTC:
