当我加载该网站并单击Wirüber uns时，它不会像再次单击按钮时那样向下滚动(在滚动之后)。它应该向下滚动到该部分的开头，当它向下滚动到第二部分时，第一部分中的图片不应该是可见的(就像第二次单击它时那样)。

当您的页面第一次加载时，#home上的set有一个负值。

#home {
  height: 100% !important;
  display: block;
  margin-top: -80px;
  padding-top: 80px;
  z-index: -1;
  position: relative;
  top: -80px;
}

当你开始滚动时，你会改变这个边距。但是，当再次滚动回顶部时，您不会将页边距重置为-80px，这将导致您在第一次加载页面和第二次单击按钮时得到不同的结果。
