title: Span Id changes in ASP.NET
body: <p>I have a span in a <code>.master</code> page that uses <code>runat="server".</code> Server-side, c# code adds to the innerHtml of this span. The span is <code>id="tickerfade"</code>; however, when it is rendered on the page the id is changed to <code>id=ctl00_tickerfade</code>. why does this happen and how can I stop it?</p>
