Ahh, that does make more sense.
Please note that CSS stands for "Cascading Style Sheets". This is used for setting the style for HTML elements on the page (for example you can set the background-color property using CSS). You cannot use CSS to redirect to another web page.
If you want to redirect, you can use the HTML code that Kub has posted. Or you can do this server side as sanjib65 suggested.
You could use the
Server.Transfer() method but only if you are "transferring" the user from web page in your website to another web page in your website.
If you are trying to redirect the user to a webpage/website that is out side of your website/server then you need to use the
Server.Redirect() method.
