Question

我有div，想在div的右上角放置图章之类的图像

这是我已经完成的代码

.package-item-header {
  margin-top:20px;
  margin-left:20px;
  width: 200px;
  background-color: #efefef;
  text-align: center;
  font-size: 24px;
  position: relative;
  padding: 20px;
}
.package_stamp{
  height: 30px;
  width: 30px;
  background: url('https://i.imgur.com/bPR0GVD.png') 50px no-repeat;
  background-position: center;
  position:absolute;
  top:0;
  right:0;
}

<div class="package-item-header">
  <div class="package_stamp"></div>
  GOLD
</div>

但是它只是放在div的右下角，而不是在div上方。

我该如何做，但背景要透明？

Answer 1

您可以将top和right的负值与position: absolute结合使用，将图像移到其父图像上。 overflow:visible确保图像在父母的边界之外可见，但是在这种情况下不是必须的。

我还添加了background-size: cover，以使背景图片填充元素。

.package-item-header {
  margin-top: 20px;
  margin-left: 0;
  width: 200px;
  background-color: #efefef;
  text-align: center;
  font-size: 24px;
  position: relative;
  padding: 20px;
  overflow: visible;
  float: left;
}

.package_stamp {
  height: 60px;
  width: 60px;
  background: url('https://i.imgur.com/bPR0GVD.png') 50px no-repeat;
  background-position: center;
  position: absolute;
  top: -20px;
  right: -20px;
  background-size: cover;
  z-index: 1;
}

<div class="package-item-header"><img class="package_stamp" />GOLD</div>
<div class="package-item-header"><img class="package_stamp" />GOLD</div>
<div class="package-item-header"><img class="package_stamp" />GOLD</div>

.package-item-header {
    margin-top:20px;
    margin-left:20px;
    width: 100px;
    background-color: #efefef;
    text-align: center;
    font-size: 24px;
    position: relative;
    padding: 20px;
    position: relative;
    float: left;
}

.package-item-header:hover .package_stamp {
  opacity: .5;
}

.package_stamp{
      height: 80px;
      width: 80px;
      background: url('https://i.imgur.com/bPR0GVD.png') no-repeat;
      background-position: center;
      position:absolute;
      top:-25px;
      right:-25px;
      background-size: contain;
      z-index: 1;
}

img.package_stamp {
  border: 1px solid white;
}

<div class="package-item-header"><div class="package_stamp"></div>GOLD</div>
<div class="package-item-header"><div class="package_stamp"></div>GOLD</div>
<div class="package-item-header"><div class="package_stamp"></div>GOLD</div>
