在CSS掩码后面添加图像

Question

我怎样才能使背景图像看起来像在电话上显示？因此，我有iPhone蒙面，我想把一个图像在屏幕上的电话。我该怎么做？我试着玩z-索引，但不起作用。以下是我想要达到的目标

​

​

div{
  width: 302px;
  height: 605px;
  background-image: url(https://www.apple.com/v/iphone-xs/d/images/overview/hardware_display_iphonexsmax_gold_portrait_large_2x.jpg);
  background-size: 302px 605px;
  background-repeat: no-repeat;
  -webkit-mask-size: 302px 605px;
  -webkit-mask-image: url(https://www.apple.com/v/iphone-xs/d/images/overview/hardware_display_iphonexsmax_gold_portrait_mask_large.svg);
  -webkit-mask-repeat: no-repeat;
  position: relative;
  z-index: 2;
}

.background{
  position: absolute;
  top: 0;
  left: 0;
  z-index: 1;
  width: 265px;
  height: 571px;
  background-image: url(https://www.apple.com/v/iphone-xr/d/images/overview/screen_display_iphonexr_large_2x.jpg);
  background-size: 265px 571px;
}

<div>
</div>

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

Answer 1

您遇到的问题是，您应用到手机上的div样式也被应用到.background中。通过给手机它是一个单独的类，你可以单独地给它们打样式。

我在下面更新了你的例子。

​

    .phone {
  width: 302px;
  height: 605px;
  background-color: white;
  background-image: url(https://www.apple.com/v/iphone-xs/d/images/overview/hardware_display_iphonexsmax_gold_portrait_large_2x.jpg);
  background-size: 302px 605px;
  background-repeat: no-repeat;
  -webkit-mask-size: 302px 605px;
  -webkit-mask-image: url(https://www.apple.com/v/iphone-xs/d/images/overview/hardware_display_iphonexsmax_gold_portrait_mask_large.svg);
  -webkit-mask-repeat: no-repeat;
  position: absolute;
  z-index: 2;
}

.background {
  position: absolute;
  top: 20px;
  left: 20px;
  z-index: 1;
  width: 280px;
  height: 580px;
  border-radius: 10px;
  background-image: url(https://www.apple.com/v/iphone-xr/d/images/overview/screen_display_iphonexr_large_2x.jpg);
  background-size: cover;
}

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

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