Question

我有以下div。

.div {
width:100%;
padding-bottom:20%;
background-color:blue;
}

<div class="div"></div>

我已经尝试了很长一段时间才找到一种方法来垂直修复这个div在网页的正中心但是找不到任何令人满意的东西。要清楚这一点，当你在网页上下滚动时，这个完全响应的div不能移动，应该固定在网页的正中心，上面和下面有相同的空间。有人可以帮忙吗？

Answer 1

当你开始滚动时，你应该给它一个position: fixed;以保持它的位置。接下来，将顶部和底部的20％放在边缘20％处。

＆＃13;

body {
  background-color: red;
  margin: 0;
}
div {
  position: fixed;
  top: 20%;
  bottom: 20%;
  width:100%;
  padding-bottom:20%;
  background-color:blue;
}

＆＃13;

<div></div>

＆＃13;

Answer 2

您可以使用vh居中到视口。

从您的div中移除padding并使用margin-top: 20vh

即便：

＆＃13;

html {
  height: 100%;
}

body {
  margin: 0;
  border: 0;
  padding: 0;
  height: 100%;
  background-color: #000;
  overflow: hidden;
}

.content {
  margin-top: 20vh;
  height: 60%;
  background-color: #fff;
  overflow: auto;
}

.content-text {
  font-size: 13px;
  font-family: "Segoe UI", Aria, sans-serif;
  padding: 1em;
}

    <h1>What is Lorem Ipsum?</h1>
    <p>
      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>
    <h2>Why do we use it?</h2>
    <p>
      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).
    </p>
    <h3>Where does it come from?</h3>
    <p>
      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.
    </p>
    <p>
      The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions
      from the 1914 translation by H. Rackham.
    </p>
    <h3>Where can I get some?</h3>
    <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.
