Most Microsoft® ASP.NET controls are designed to be browser independent; they generate plain HTML markup that the majority of browsers easily understand and process. As a page developer, you can control to some extent the version of the HTML language used to generate the browser response. Some of the ASP.NET controls (for example, validation server controls) detect the capabilities of the underlying browser and adapt their response accordingly. In many cases, this means that the markup is enriched with script code that enhances the control's overall functionality.
