图像样式"object-fit: contain"在谷歌浏览器版本 72.0.3626.109 中被破坏



我最近已更新为Mac中的Google Chrome Version 72.0.3626.109 (Official Build) (64-bit),并且现在正在破裂。

具有位复杂的嵌套标记背后的原因是因为我需要显示位于div中心的图像的图像分别为不同的大小,但在Square Div中成比例地调整了大小。因此,在更新新的Google Chrome之前,所有这些都可以正常工作。

.g-parent {
  width: 150px;
}
.parent {
  position: relative;
  padding-bottom: 100%;
  background-color: gray;
}
.child {
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  position: absolute;
  padding-bottom: 100%;
}
.my-img {
  width: 100%;
  height: 100%;
  display: block;
  -o-object-fit: contain;
  object-fit: contain;
}
<div>
  <img class="my-img" src="https://dummyimage.com/400x200/000/fff" />
</div>
<h4>Show above image inside below div</h4>
<div class="g-parent">
  <div class="parent">
    <div class="child">
      <img class="my-img" src="https://dummyimage.com/400x200/000/fff" />
    </div>
  </div>
</div>

不太确定为什么它起作用,因为在这种情况下height:100%应该失败,因为父容器中没有设置高度。因此,实际行为似乎是正确的行为。

您可以使图像为position:absolute来解决此问题:

.g-parent {
  width: 150px;
}
.parent {
  position: relative;
  padding-bottom: 100%;
  background-color: gray;
}
.child {
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  position: absolute;
  padding-bottom: 100%;
}
.child > img {
  position:absolute;
}
.my-img {
  width: 100%;
  height: 100%;
  display: block;
  -o-object-fit: contain;
  object-fit: contain;
}
<div>
  <img class="my-img" src="https://dummyimage.com/400x200/000/fff" />
</div>
<h4>Show above image inside below div</h4>
<div class="g-parent">
  <div class="parent">
    <div class="child">
      <img class="my-img" src="https://dummyimage.com/400x200/000/fff" />
    </div>
  </div>
</div>

您还可以使用一个Div简化此:

.g-parent {
  width: 150px;
}
.parent {
  position: relative;
  padding-bottom: 100%;
  background-size:contain;
  background-position:center;
  background-repeat:no-repeat;
  background-color: gray;
}
.my-img {
  width: 100%;
  height: 100%;
  display: block;
  -o-object-fit: contain;
  object-fit: contain;
}
<div>
  <img class="my-img" src="https://dummyimage.com/400x200/000/fff" />
</div>
<h4>Show above image inside below div</h4>
<div class="g-parent">
  <div class="parent" style="background-image:url(https://dummyimage.com/400x200/000/fff)">
  </div>
</div>

.g-parent {
  width: 150px;
}
.parent {
  position: relative;
  padding-bottom: 100%;
  background-color: gray;
}
.child {
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  position: absolute;
  padding-bottom: 100%;
}
.my-img {
  width: 100%;
  height: 100%;
  display: block;
  -o-object-fit: contain;
  object-fit: contain;
}
<div>
  <img class="my-img" src="https://dummyimage.com/400x200/000/fff" />
</div>
<h4>Show above image inside below div</h4>
<div class="g-parent">
  <div class="parent">
    <div class="child">
      <img class="my-img" src="https://dummyimage.com/400x200/000/fff" />
    </div>
  </div>
</div>
