Navbar Beets
The .navbar class is reserved for regular Bootstrap which can be used with Beets and there for we need to use a prefix of "-b" for our navbar.
Markup
The contents of the left, right and middle columns are aligned accordingly. Since the navbar is built of .col you can remove the middle column if you don't need it. Also, you can set fixed width for columns that you know don't need a responsive width.
