HTML Components (HTCs) are a legacy technologydeclared obsolete by Microsoft as of MSIE 10 "This topic documents a feature of Binary Behaviors, which are obsolete as of Internet Explorer 10" used to implement components in script as Dynamic HTML (DHTML) "behaviors"Introduction to DHTML Behaviors in the Microsoft Internet Explorer web browser. Such files typically use an .htc extension and the "text/x-component" MIME type.MIME Types in IIS
An HTC is typically an HTML file (with JScript / VBScript) and a set of elements that define the component. This helps to organize behavior encapsulated in script modules that can be attached to parts of a Webpage DOM.
Example <body> <ul> <li style="behavior:url(hilite.htc)">Example</li> </ul> </body>
In this example, the li element is given the behavior defined by "hilite.htc" (a file that contains JScript code defining highlight/lowlight actions on mouse over). The same hilite.htc can then be given to any element in the HTML page - thus encapsulating the behavior defined by this file.
