Question

HTML标记：

<div class="item">
    <a href="url">
        <img src="photo.jpg" />
    </a>
</div>

此CSS在悬停时缩放图像：

.item a img {
   transition: all 0.2s linear;
}

.item a:hover img {
   transform: scale(1.05);
}

此CSS在悬停时添加了叠加层：

.item a {
    position: relative;
}

.item a:before {
    content: "";
    display: block;
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    background: none no-repeat center center;
    transition: all .3s linear;
}
.item a:hover:before {
    background:rgba(0,0,0, 0.5) url('img/zoom.png') no-repeat center center;
}

每个人本身都很好。但是，当我尝试使用两个CSS时，只有缩放工作;叠加层坏了。

简单地说，如何编写CSS来组合这两种效果？

您可以尝试将private class WaitSec extends AsyncTask<Void, Void, Boolean>{ @Override protected Boolean doInBackground(Void... params) { try { Thread.sleep(2000); } catch (InterruptedException e) { e.printStackTrace(); } if(CheckSomeUtil.isItOk()) { return true; } else { return false; } } @Override protected void onPostExecute(Boolean aBoolean) { if(aBoolean) // in this line. is i want to set listener. super.onPostExecute(aBoolean); } }添加到绝对定位元素。

z-index:1

.item a img {
  transition: all 0.2s linear;
}
.item a:hover img {
  transform: scale(1.05);
  vertical-align: top;
}
.item a {
  position: relative;
  display: inline-block;
}
.item a:before {
  content: "";
  display: block;
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  background: none no-repeat center center;
  transition: all .3s linear;
  z-index: 1;
}
.item a:hover:before {
  background: rgba(0, 0, 0, 0.5) url('//dummyimage.com/50') no-repeat center center;
}
