[DotNetDevelopment] Making a ASP.NET web application cross browser compatibility

[Thamizh Jain]

I have developed a webapplication in asp.net 2.0. How do I make it
capable of running in all the browsers (IE 4.0, 5.0, 6.0, 7.0,8.0,
Opera, Chrome, Mozilla, safari, Netscape) without having changes in
the UI. Is there any readymode code for this issue?
