What is needed ONLY for Twitter Bootstrap's Popover?

Question

I understand I can go to http://twitter.github.com/bootstrap/customize.html#components and select the only the components I need to make the popovers work.

I updated the js and css to link to the files downloaded. I'm not getting any errors but I'm also not getting the popover.

Original Question:
I'd like to add the popover to my site but the bootstrap's standard css file conflicts with my existing styling. From http://twitter.github.com/bootstrap/1.4.0/bootstrap.min.css, can someone tell me which bits and pieces I need just for the popovers? I used Firebug to see what classes are called but I'm obviously missing something. I don't have to use Boostrap's Popover, I'm open to other plugins if they are as easy to use.

You can customize your download right on the twitter bootstrap site (here). In order to get the css just for the popover just select that and uncheck everything else, that you will allow you to download both the regular and responsive classes used on the popover alone.
