Nav Bar Animation Only Happens Once

Hello world! I am trying to clone Apple’s MOBILE nav bar animation. The first time you open the nav bar, all the nav bar links fade in as expected. But if you close the nav bar and try again, the links don’t fade in like they’re supposed to. In other words, my animation only happens on the first try, per page load. Can a smart person please help me figure this out? I am stuck. Thank you. :slight_smile:
