Not sure if the dev will see this, but it would be nice if it was a little easier to get to the table of contents as well. My suggested code change. (quick a dirty example)

  .menu {
    margin-bottom: 1.5em;
    position: sticky;
    top: 0;
    z-index: 1000;
    background: #fff;
    padding: 10px;
  }
