HTML Components

Not to be confused with Web Components.

HTML Components (HTCs) are a legacy technology[1] used to implement components in script as Dynamic HTML (DHTML) "behaviors"[2] in the Microsoft Internet Explorer web browser. Such files typically use an .htc extension and the "text/x-component" MIME type.[3]

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.
