The Silverlight plug-in defines the area that the Silverlight-based application is displayed in. You embed the plug-in in a host HTML page; you can either position the plug-in somewhere inline in the HTML page display or have the plug-in take up the entire HTML page. Because of this, there are two frames of reference when positioning Silverlight objects:

  • Within the plug-in: Position objects on the Silverlight surface within the plug-in’s bounding box. Most of the layout overviews describe this type of positioning.
  • Within the HTML: The entire plug-in and all the objects positioned within it are subject to where you place the plug-in in HTML. For more information on the plug-in, see Adding Silverlight to a Web Page by Using HTML or JavaScript.
