A bootstrap carousel scrolls my fixed top navigator

Question

I have fixed top navigation for the personal site that I am doing. I added a rather large boot carousel under this, but when I scroll down, the carousel scrolls above the title hide the navigation. I put a link to the version of the site hosted on github pages and included some relevant code snippets below along with a link to the repository. Thank you in advance for any help you can provide.

To have a fixed navigation bar on top, use bootstrap navbar

<nav class="navbar navbar-default navbar-fixed-top">
  <div class="container">
    ...
  </div>
</nav>
