固定div可见时，以下内容不应滚动

Question

期望什么？

加载程序加载时，我不希望下面的内容滚动。

我尝试了z-index，position（相对于其他元素）。 但是他们没有用。

body,
html {
  margin: 0;
  padding: 0;
}

.fixed {
  display: flex;
  color: white;
  align-items: center;
  justify-content: center;
  position: fixed;
  background: rgba(0, 0, 0, 0.5);
  height: 100vh;
  width: 100vw;
  z-index: 9999
}

.content {
  height: 1300px;
  background: red;
  z-index: 0;
}


/* Please ignore the below code, as it has nothing to do with the problem */

.loader {
  color: #ffffff;
  font-size: 90px;
  text-indent: -9999em;
  overflow: hidden;
  width: 1em;
  height: 1em;
  border-radius: 50%;

将overflow: hidden;添加到html选择器

.fixed {

Answer 2

将溢出移至另一个包装器。实际上它在视口上，并且固定元素也相对于视口定位，因此它无法隐藏滚动条

body,
html {
  margin: 0;
  padding: 0;
}

.fixed {
  display: flex;
  color: white;
  align-items: center;
  justify-content: center;
  position: fixed;
  background: rgba(0, 0, 0, 0.5);
  height: 100vh;
  width: 100vw;
  z-index: 9999;
}

.content {
  height: 1300px;

Answer 3

setting the position of .content to fixed will also fix the problem. you may also need to set the width in that case:

    .content {
      height: 1300px;
      background: red;
      z-index: 0;
      position:fixed;
      width:100%;
    }
