我用anchor元素的scroll-margin-top属性解决了这个问题

scroll-margin-top: 100px;

https://developer.mozilla.org/en-US/docs/Web/CSS/scroll-margin-top

对于Chrome/Safari/Firefox，你可以添加一个display: block，并使用负边距来补偿偏移量，如下所示:

a[name] {
    display: block;
    padding-top: 90px;
    margin-top: -90px;
}

参见示例http://codepen.io/swed/pen/RrZBJo

这对我来说很管用:

HTML链接到锚点:

<a href="#security">SECURITY</a>

HTML锚:

<a name="security" class="anchor"></a>

CSS:

.anchor::before {
    content: "";
    display: block;
    margin-top: -50px;
    position: absolute;
}

在我的纯粹主义思想中，这感觉有点俗气，但作为css的唯一解决方案，你可以使用:target选择器为活动锚定元素添加填充:

html, body {height:100%; min-height:100%; margin:0;} body {min-height:200%;} header {display:inline-block; position:fixed; font-size:1.5em; height:100px; top:0; left:0; right:0; line-height:100px; background:black; text-align:center;} header a {color:#fff;} section {padding:30px; margin:20px;} section:first-of-type, section:target {padding-top:130px;} <header><a href="#one">#One</a> <a href="#two">#two</a> <a href="#three">#three</a></header> <section id="one"><h1>One</h1>Aenean lacinia bibendum nulla sed consectetur. Nullam id dolor id nibh ultricies vehicula ut id elit. Integer posuere erat a ante venenatis dapibus posuere velit aliquet.</section> <section id="two"><h1>Two</h1>Aenean lacinia bibendum nulla sed consectetur. Nullam id dolor id nibh ultricies vehicula ut id elit. Integer posuere erat a ante venenatis dapibus posuere velit aliquet.</section> <section id="three"><h1>Three</h1>Aenean lacinia bibendum nulla sed consectetur. Nullam id dolor id nibh ultricies vehicula ut id elit. Integer posuere erat a ante venenatis dapibus posuere velit aliquet.</section>

我认为这种方法更有用:

<h2 id=“bar” title=“Bar”>Bar</h2>

[id]:target {
    display: block;
    position: relative;
    top: -120px;
    visibility: hidden;
}

[id]:target::before {
    content: attr(title);
    top: 120px;
    position: relative;
    visibility: visible;
}

我使用@Jpsy的答案，但出于性能原因，我只在URL中存在散列时设置计时器。

$(function() {
      // Only set the timer if you have a hash
      if(window.location.hash) {
        setTimeout(delayedFragmentTargetOffset, 500);
      }
  });

function delayedFragmentTargetOffset(){
      var offset = $(':target').offset();
      if(offset){
          var scrollto = offset.top - 80; // minus fixed header height
          $('html, body').animate({scrollTop:scrollto}, 0);
          $(':target').highlight();
      }
  };
