HTML Applications (HTAs) are full-fledged applications. These applications are trusted and display only the menus, icons, toolbars, and title information that the Web developer creates. In short, HTAs pack all the power of Microsoft® Internet Explorer—its object model, performance, rendering power, protocol support, and channel–download technology—without enforcing the strict security model and user interface of the browser. HTAs can be created using the HTML and Dynamic HTML（动态HTML，即DHTML） that you already know.

In short, HTAs pack all the power of Internet Explorer—its object model, performance, rendering power, protocol support, and channel-download technology—without enforcing the strict security model and user interface of the browser.
