Question

我有.gridster项目（块绝对定位，宽度和高度固定，并且有自动溢出），在内部我想要红色块（绝对位于右下角）以保持在他开始的位置，但是当我使用滚动时，红色块跟随滚动。

＆＃13;

.gridster-item {
    width: 400px;
    height: 200px;
    position: relative;
    overflow: auto;
    background-color: rgb(204, 214, 249);
}

.resizer {
    position: absolute;
    bottom: 0;
    right: 0;
    width: 10px;
    height: 10px;
    background-color: red;
}

Answer 1

您需要将{em>包装与position: relative一起使用，以便绝对定位的元素将相对定位到它不受滚动 div的影响：

#wrapper {
  display: inline-block; /* or "inline-flex" which also only takes the content's width */
  position: relative;
}

.gridster-item {
  width: 400px;
  height: 200px;
  /*position: relative;*/
  overflow: auto;
  background-color: rgb(204, 214, 249);
}

.resizer {
  position: absolute;
  bottom: 0;
  right: 17px; /* 17px because that's a typical width of the scrollbar */
  width: 10px;
  height: 10px;
  background-color: red;
}

<div id="wrapper">
  <div class="gridster-item">
    <div class="content">
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
      <p>Lorem Ipsun dolor amet</p>
    </div>
    <div class="resizer"></div>
  </div>
</div>

相对于块固定的位置，而不是视口
