I'm trying to make a simple one-page responsive site to learn web development and I'm using Foundation 6. Ran into a problem with the dropdown when the screen size becomes small. The dropdown works fine at large and medium sizes, but not on small/mobile.

Album showing the site in desktop and mobile sizes, the html file and the css file: http://imgur.com/a/Y3X5r

In the first screenshot, I won't actually have a dropdown for the Home link. I only added that dropdown to test if it works at desktop size. I would upload the files themselves, but I don't know where to do that.
