Automatically hide bar

Hi,

Great plugin. Is there a way I can set the cookie message bar to automatically disappear after a few seconds of being displayed, i.e. without the user having to click the accept button on the message bar?

Also, can I make the message less obtrusive, e.g. by making it transparent instead of black and also smaller?

Thanks
