Responsive sidebar: first jQuery pen

Hi everyone, I’ve made my first responsive sidebar, using jQuery (trying to grasp this) and coded by myself.

As any first project, I’m sure there’s room for improvement and optimization, so please take a look at the project here (https://codepen.io/dcosta89/pen/gOaeabv) and tell me what I could’ve done better.

Thanks to you all!

First of all , Good job…
What you might want to do is make the cursor into a pointer when the user is hovering the whole nav link, not just the paragraph link.
Thats all, Great work!!
