css - 在多列文本中，将 div 粘贴到底部

Question

我试图在 CSS3 多列文本中将一个 div 粘贴到列的底部。

显然

position:absolute, bottom:0

打破专栏。有什么办法可以达到这种效果吗？或者也许有更有效的方式来组织多列文本？

.col {
  -webkit-column-count: 2;
  /* Chrome, Safari, Opera */
  -moz-column-count: 2;
  /* Firefox */
  column-count: 2;
}

.bottom {
  border: 1px solid #777;
}

<div class="col">
  <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It
    has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop
    publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>

  <p>Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to
    using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their
    infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).</p>


  <p>Where does it come from? Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College
    in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33
    of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes
    from a line in section 1.10.32.</p>

  <p class="bottom">The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions
    from the 1914 translation by H. Rackham.</div>

好的，非常感谢您的回答，但是我好像不是很清楚:

所以黄色 block 是卡在第二列底部的那个，这是我正在努力实现的目标。

使用 CSS 列，并且没有脚本，只有一种方法可以动态地完成这项工作，那就是复制 .bottom 项，隐藏一个并绝对定位另一个。

隐藏的需要确保在计算列高的总大小时考虑其内容的大小，否则定位的将与之前的内容重叠。

.col {
  position: relative;
  -webkit-column-count: 2;  /* Chrome, Safari, Opera */
  -moz-column-count: 2;     /* Firefox */
  column-count: 2;
}

.bottom {
  position: absolute;
  bottom: 0;
  border: 1px solid #777;  
}

.bottom-hidden {
  visibility: hidden;
  border: 1px solid #777;  
}

如果文本的大小多少已知，另一种可能的选择是给倒数第二列元素一个底部边距，匹配最后一个元素的高度，尽管这个固定高度需要在不同的屏幕尺寸上进行很好的测试，所以它不重叠。

.col {
  position: relative;
  -webkit-column-count: 2;  /* Chrome, Safari, Opera */
  -moz-column-count: 2;     /* Firefox */
  column-count: 2;
}

.col *:nth-last-child(2) {
  margin-bottom: 200px;
}

.bottom {
  position: absolute;
  left: calc(50% + 10px);       /*  Safari needed this  */
  width: calc(50% - 20px);      /*  Safari needed this  */
  bottom: 0;
  border: 1px solid #777;  
}
