HTML Server Controls

When HTML tags are used in an ASP.NET page, they’re ignored by the server

and passed to the browser unchanged; the browser renders them as it would any

other HTML page. The simple addition of the runat="server" attribute turns

an HTML tag into an HTML control, which we can then access and alter through

our code by means of the identifier given in the control’s id attribute. The fol-

lowing reference lists all the useful properties, methods, and events of ASP.NET’s

HTML controls.
