Intro Section with Dropdown Navigation (Scss + Js)

Hi George, it also took me some time to figure out how to work the overlay, and as a practice afterwards I wrote a simplified version of this site using a CodePen. It's a bit different to how I wrote my challenge, but in any case, it shows how you can use little code to make everything work. You can check out the overlay there: https://codepen.io/elaineleung/pen/poLpzge

As for the JS, it's quite a lot! I wrote mine in React so I can't exactly compare the two, but even with my CodePen, you can see that you don't need a lot of code (I just had 12 lines). For instance, instead of using add and remove on classList, you can try toggle instead. I think you'll find that when you don't need to add and remove the class, your code will shrink down by at least half. Also, I see that you used let instead of const variables for your DOM elements; since these aren't bound to change, you can use const instead, as that is the common practice.

Anyway, hope this helps you out!
