title: Can I change the opacity of the navbar in twitter bootstrap?
body: <p>I stumbled onto this <a href="https://testflightapp.com/" rel="noreferrer">site</a>: and started thinking.  Is this possible using twitter's <a href="http://twitter.github.com/bootstrap/" rel="noreferrer">bootstrap</a>? I don't see an opacity setting in the css file?  Is it as easy as adding it.</p>
