The HtmlContainerControl Class

Any HTML control that requires a closing tag inherits from the HtmlContainer class. 
For example, elements such as <a>, <form>, and <div> always use a closing tag.
Elements such as <img> and <input> are used only as stand-alone tags.
HtmlAnchor, HtmlForm, and HtmlGenericControl classes inherit from HtmlContainerControl
HtmlInputImage and HtmlInputButton do not.
The HtmlContainer control adds two properties to those defined in HtmlControl.
HtmlContainerControl Properties
Property         Description
InnerHtml        The HTML content between the opening and closing tags of the control. 
InnerText        The text content between the opening and closing tags of the control.
