I want some flexibility in my css style block so i decide to inject some server side code, f.e.

```
#defaultGameContainer {
            position: relative;
            width: @(SiteConfig.Instance.Game.Width + "px");
            height: 600px;
            top: 100px;
            left: 50%;
            margin-left: -480px;
        }

```

But it seems not work, i have a error in VS like 'unexpected characters sequence...'
Are we restricted to use Razor syntax in css?
Thanks.
