The navbar is complete. I added a layer of abstraction by placing the variables in their seperate file _navbar_vars.scss. This way you can edit them without issue. I also divided the variables into screen sizes so if something looks wrong on one size, it will not affect the other sizes. Finally, I started a global variable file called globals.scss. These variables are meant to serve as constants throughout multiple style sheets. Right now the only things in there are the min and max values for the screen sizes medium, small and large.
