While this looks good aesthetically, this is a prime example of needlessly using JavaScript for the hell of it. This is like an anti best practice. It loads 4 extra resources (Angular, Angular Cookie, Angular UI Bootstrap and the custom bootstrap.js) for no legitimate reason. And the CSS is inexplicably written using selectors like the following: "#page-wrapper:not(.active)". Why not target "#page-wrapper" and then "#page-wrapper.active" instead?

Your CSS quibble is a matter of taste, you have a legitimate complaint about the JS so I wouldn't muddy it with a taste based comment about CSS verbosity.
