Can't get blueprint CSS plugins working?

I am trying to use blueprint css, and everything seems to be working, but I can't seem to get any of the plugins loaded up.

I tried just including the requisuite CSS files, but I think there must be another step because even though the browser sees the CSS files the elements on the page are not changing (in firebug on Ch开发者_JAVA技巧rome I get there are no rules on this stylesheet when I try to look at the plugin css page) .

What do I need to do to get the Vanilla blueprint CSS + the buttons, fancy-type, link-icons, and rtl going? Just all the stuff they include in the default download.

I feel like I am missing something besides just including CSS.

I was using

<link rel="stylesheet" href="~/Content/plugins/fancy-type/screen.css" type="text/css" media="screen, projection" />

instead of

<link href="@Url.Content("~/Content/plugins/fancy-type/screen.css")" rel="stylesheet" type="text/css" />
