将Bootstrap固定导航栏的底部与div的顶部对齐

Question

I have a fixed navbar on the top of my page and a scrollspy set up with animated scrolling. 我在页面顶部有一个固定的导航栏，并设置了带有动画滚动的scrollspy。 However, when I click a navigation link, the page scrolls to the point where the top of the navbar aligns with the top of the anchored div . 然而，当我点击一个导航链接，页面滚动的地步导航栏的顶部对齐与锚顶 div 。 I'd like the bottom of the navbar to align with the top of the anchored div so as to not cover any content in that anchored div . 我希望导航栏的底部与锚定div的顶部对齐，以便不覆盖该锚定div任何内容。 How can I do this? 我怎样才能做到这一点？

As far as my code goes, I am starting from this example from W3schools. 就我的代码而言，我是从W3schools的示例开始的。

To scroll at the top of each sections instead of the additional offset of 50px, you can just subtract 50 from these two: 要在每个部分的顶部滚动，而不是在50px的附加偏移量上滚动，您可以从这两个部分中减去50：

$('html, body').animate({
        scrollTop: $(hash).offset().top-50
      }, 800, function(){

        // Add hash (#) to URL when done scrolling (default click behavior)
        window.location.hash = hash-50;
      });

Original snippet: (Scrolls to 50 offset from top) 原始代码段：（滚动到顶部偏移50）
