Question

我正在使用HTML中的CSS创建粘性标头。效果很好，但是如果第一个标头使用两行，则第二个标头将跟随使用这两行作为背景，即使它应该使用一行。仅当屏幕尺寸宽度较小时，才会出现此问题。看一下屏幕截图，以更好地理解它。（对不起，我正在努力把问题说出来）

first header - with long title

second header - with short title

这是html和CSS代码：

<!DOCTYPE html>


  
<style>

body {
  margin-top: 0px;

}
.header {
  padding:1px 0px;
  background: #fff;
  color: #000;
  }

.content {
  padding: 0px;
}

.sticky {
  position: sticky;
  top: 0px;
  width: 100%;
}

.sticky + .content {
  padding-top: 0px;
}
</style>







<div class="sticky header" ><p><strong>FIRST HEADER - FIRST HEADER - FIRST HEADER</strong></p></div>
<p>What is Lorem Ipsum?
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>

<p>Where does it come from?
Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.
em Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.</p>

<div class="sticky header"><p><strong>SECOND HEADER</strong></p></div>
<p>Why do we use it?
It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).Where can I get some?</p>
<p>There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.</p>

Answer 1

首先，在浏览器中是否支持position：sticky足以进行链接？

https://caniuse.com/#search=position%3A%20sticky

第二，我在您的html中看不到带有“内容”类的容器

解决方案：

将粘性div放在内容div中：

html：

<div class="content">

   <div class="sticky header"><p><strong>SECOND HEADER</strong></p></div>

      <p>Why do we use it?</p>

   </div>

</div>

Answer 2

实际上，第二个标头不使用第一个标头的高度，相反，它覆盖了第一个标头，因此您认为第一个标头是隐藏的。如果您进一步延长第一个标题，则会更清楚地看到它。

要最轻松地解决此问题，可以使用css + js预设，例如语义UI：Sticky | Semantic UI。

Answer 3

在sticky内使用div元素，还将position: -webkit-sticky;与position: sticky;一起使用

body {
  margin-top: 0px;

}
.header {
  padding:1px 0px;
  background: #fff;
  color: #000;
 }

.content {
  padding: 0px;
}

.sticky {
  position: sticky;
  position: -webkit-sticky;
  top: 0px;
  width: 100%;
  height: 10%;
  border:1px solid red;
}

.sticky + .content {
  padding-top: 0px;
}

  
<html>
<div class="content">
<div class="sticky header" ><p><strong>FIRST HEADER - FIRST HEADER - FIRST HEADER</strong></p></div>
