If you look at index.html the tag encompasses all the classes -- menu, icon-menu, icon-close and jumbotron. So (here's the question) why do you need to include an animation movement command for both ('.menu') and ('body')? Shouldn't the "menu" move with the "body" since it's contained within it? (It doesn't, by the way, if you try it)
I can get the code to work for hiding and displaying the menu, but I'm trying to understand the bigger picture.
Thanks for the help!
