我有以下html：

<html>
  <head>
    <title>asd</title>
  </head>
  <body>
    <div class="wrapper">
      <div class="slide slide1"></div>
      <div class="slide slide2"></div>
      <div class="slide slide3"></div>
      <div class="slide slide4"></div>
    </div>
  </body>
</html>

和以下css：

* { box-sizing: border-box; }

.wrapper {
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  align-items: stretch;
  justify-content: center;
}

.slide {
  position: relative;
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  -webkit-box-orient: vertical;
  -moz-box-orient: vertical;
  -webkit-box-direction: normal;
  -moz-box-direction: normal;
  -webkit-flex-direction: column;
  -ms-flex-direction: column;
  flex-direction: column;
  -webkit-box-align: center;
  -moz-box-align: center;
  -ms-flex-align: center;
  -webkit-align-items: center;
  align-items: center;
  -webkit-box-pack: center;
  -moz-box-pack: center;
  -ms-flex-pack: center;
  -webkit-justify-content: center;
  justify-content: center;
  width: 100%;
  height: 100vh;
  transition: all 250ms cubic-bezier(0.25, 0.46, 0.45, 0.94);
  webkit-transition: all 250ms cubic-bezier(0.25, 0.46, 0.45, 0.94);
}

.slide1 {
  background-image: url('http://hdwpro.com/wp-content/uploads/2016/03/Fantastic-Full-HD-Wallpaper.jpg');
    background-size: cover;
    background-position: center;
    background-repeat: no-repeat;
}

.slide2 {
  background-image: url('http://hdwpro.com/wp-content/uploads/2016/03/Galaxy-Space-Full-HD-Wallpaper.jpg');
    background-size: cover;
    background-position: center;
    background-repeat: no-repeat;
}

.slide3 {
  background-image: url('http://hdwpro.com/wp-content/uploads/2016/03/Landscape-Full-HD-Wallpaper.jpg');
    background-size: cover;
    background-position: center;
    background-repeat: no-repeat;
}

.slide4 {
  background-image: url('http://hdwpro.com/wp-content/uploads/2018/10/Free-Desktop-Background.jpg');
    background-size: cover;
    background-position: center;
    background-repeat: no-repeat;
}

.slide:hover {
  transform: scale(1.2);
  z-index:20;
}

div flex里面的变焦似乎是变换 scale 上的一个小故障，我也想找到一种方法来缩放div内的背景图像而不是div（将在视口外缩放） .

我尝试添加父包装，但它缩放div而不是背景图像 .

正如您在此Codepen中看到的那样：https://codepen.io/pufosme/pen/MZWWpM

谢谢 ！

    需要进入父div并添加 overflow:hidden （抱歉我的英文不好 . ）

    codepen链接https://codepen.io/dgknca/pen/ebYmRW

    * { box-sizing: border-box; }

.wrapper {
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  align-items: stretch;
  justify-content: center;
}

.parent {
  flex:1; 
  height: 100vh;
  overflow:hidden;
}

.slide {
  position: relative;
  display: -webkit-box;
  display: -moz-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  -webkit-box-orient: vertical;

    就个人而言，我会在每张幻灯片中使用IMG（使用object-fit和object-position来替换背景属性） . 然后缩放图像而不是幻灯片，并在每张幻灯片上设置 overflow: hidden .

    喜欢这个https://codepen.io/anon/pen/bOGNoN

    .slide {
  ...
  width: 100%;
  height: 100vh;
  overflow: hidden;
}

.slide img {
  object-fit: cover;
  object-position: center;
  width: 100%;
  height: 100%;
  transition: all 250ms cubic-bezier(0.25, 0.46, 0.45, 0.94);
  webkit-transition: all 250ms cubic-bezier(0.25, 0.46, 0.45, 0.94);
}

.slide:hover img {
  transform: scale(1.2);
  z-index:20;
  -webkit-box-shadow: 0px 0px 10px 0px rg-webkit-box-shadow: 0px 0px 18px 1px rgba(0,0,0,0.5);
-moz-box-shadow: 0px 0px 18px 1px rgba(0,0,0,0.5);
box-shadow: 0px 0px 18px 1px rgba(0,0,0,0.5);
}

    和HTML

    <div class="slide slide1">
  <img src='http://hdwpro.com/wp-content/uploads/2016/03/Fantastic-Full-HD-Wallpaper.jpg' />
</div>
