ASP.NET : HTML Server Control

HTML Server Control

- HTML elements in ASP.NET files are, by default, treated as text. To make these elements programmable, add a runat="server" attribute to the HTML element. This attribute indicates that the element should be treated as a server control.

- All HTML server controls must be within a <form> tag with the runat="server" attribute!

- ASP.NET requires that all HTML elements must be properly closed and properly nested.

Example
