使用带有固定位置标题的 scrollIntoView

Question

我有一个标头设置为 position: fixed 的网站。在我的一个页面上，我在一个元素上使用 scrollIntoView(true) 。我的问题是，当调用 scrollIntoView 时，该元素位于标题下方。我将如何解决这个问题，以便该元素显示在标题下方？

我正在使用 Bootstrap 框架，标头的样式为 navbar navbar-fixed-top 。

Answer 1

这有点老套，但这里有一个解决方法。

 var node = 'select your element';
var yourHeight = 'height of your fixed header';

// scroll to your element
node.scrollIntoView(true);

// now account for fixed header
var scrolledY = window.scrollY;

if(scrolledY){
  window.scroll(0, scrolledY - yourHeight);
}

编辑：

现代的解决方法是将 CSS scroll-margin-top 属性与 :target 选择器结合使用。详细描述： https ://www.bram.us/2020/03/01/prevent-content-from-being-hidden-underneath-a-fixed-header-by-using-scroll-margin-top/

Answer 2

编辑： 尽管兼容性较低（不兼容 IE）， scroll-margin-top 也将解决此问题，如 Arye Eidelman 的回答 中所述。

您可以使用 CSS 解决此问题，方法是将 padding-top 和负值 margin-top 应用于要滚动到的元素。

演示

 // For demo only, no JS needed for the solution
document.querySelector('.scroll-to-working-inline').addEventListener('click', function() {
  document.querySelector('.working-inline').scrollIntoView();
});

document.querySelector('.scroll-to-working-block').addEventListener('click', function() {
  document.querySelector('.working-block').scrollIntoView();
});

document.querySelector('.scroll-to-broken').addEventListener('click', function() {
  document.querySelector('.broken').scrollIntoView();
});

 /* Relevant styles */
.working-inline {
  padding-top: 60px;
  margin-top: -60px;
}

.working-block {
  padding-top: 60px;
  margin-top: -60px;
}

/* Allow scrolling to the top */
body {
  padding-top: 60px;
}

/* Only for the demo */
body { margin: 0; }

header {
  position: fixed;
  top: 0;
  background-color: tomato;
  color: white;
  width: 100%;
  height: 60px;
  line-height: 60px;
  text-align: center;
}

[class^='working'],
[class^='broken'] {
  font-size: 3rem;
}

 <header>
  scroll to...
  <button class="scroll-to-working-inline">working inline element</button>
  <button class="scroll-to-working-block">working block element</button>
  <button class="scroll-to-broken">broken element</button>
</header>
