Include .css files in asp.net

Question

Since virturl directory name is not fixed, I wrote code below to include .css file in .aspx page now.

<link rel="Stylesheet" href="<%= ResolveUrl("~/Css/xxx.css") %>" type="text/css" />

The question is, when I use "ResolveUrl" in tag, IDE is always barking about that all CSS classes is undefined.

Is there any better way to define .css file including?

Answer 1

You can do this with html server controls (notice the runat="server") like so:

<link rel="stylesheet" runat="server" media="screen" href="~/css/styles.css" />

This will still resolve the virtual directory for you. It should also support the css intellisense and warnings on the aspx page.
