Import CSS into your ASP.NET 2.0 Web Form/Master Page
Either ways will do for Web Form and Master Page. Place this in the pages instead of user controls.
The most common way is:
<link href="css/sgdotnet.css" rel="stylesheet" type="text/css" />
You will be suprised that by using the top code is actually compatible with older browsers not really on new browsers like IE 7 or FireFox 2.0.
In order to make sure you can support both old and new browsers, add in a new code just below that <link> tag.
<style type="type/css" media="all">
@import "css/sgdotnet.css";
</style>
Then you will not face any css problems anymore. Enjoy.
