The only thing and this can totally be a personal nitpick of mine…but the lack of a right-side scroll bar kinda bugs me. What’s funny is I didn’t notice it was missing until I was checking out the responsiveness of the site (which is fantastic btw) via shrinking my browser window down.
Other than that, it’s clean, well polished, and the colors are great. I love the navigation animations. Easy to read and navigate.
BTW there’s nothing wrong with using a boilerplate, it exists for the exact reason you used it. Which is to speed up production time. Could you have coded this whole thing from scratch? Absolutely, but you know how to do that obviously. It comes down to working smarter not harder and using the tools you have at your disposal. IE: boilerplates and other frameworks.
