CSS-将div对齐到其父div的底部

问题描述

我正在尝试将div＃alignBottom1和＃alignBottom2向下对齐，而不移除父div的左浮点，并且不使用绝对位置或边距顶部。

我该怎么办？

这是我的代码：

#TotContainer {
  height: 900px;
}

#container {
  max-height: 90%
}

.col-sm-6 {
  width: 50%;
  float: left;
  height: 100%;
  padding: 10px;
}

.col-sm-12 {
  width: 100%;
  float: left;
  background: yellow;
}

* {
  -webkit-Box-sizing: border-Box;
  -moz-Box-sizing: border-Box;
  Box-sizing: border-Box;
}

<div id="TotContainer">
  <div id="container">
    <div class="col-sm-6" style="background:blue;">XXXXXX</div>
    <div class="col-sm-6" style="background:red;">
      <div id="alignBottom1">Text to align at the bottom 1</div>
      <div id="alignBottom2">Text to align at the bottom 2</div>
    </div>
    <div class="col-sm-12">footer</div>
  </div>
</div>

感谢您的帮助！

解决方法

如果将父容器转换为Flexbox，则可以轻松完成此操作。

在您的示例中，我给了父级一个高度值，以便您可以看到使用flexbox并将内容对齐到父级末尾的效果。

#alignBottom {
    display: flex;
    flex-flow: column nowrap;
    justify-content: flex-end;
    height: 100px; /* giving the element a height to exaggerate the effect */
}

#TotContainer {
  height: 900px;
}

#container {
  max-height: 90%
}

.col-sm-6 {
  width: 50%;
  float: left;
  height: 100%;
  padding: 10px;
}

.col-sm-12 {
  width: 100%;
  float: left;
  background: yellow;
}

* {
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
}

<div id="TotContainer">
  <div id="container">
    <div class="col-sm-6" style="background:blue;">XXXXXX</div>
    <div id="alignBottom" class="col-sm-6" style="background:red;">
      <div id="alignBottom1">Text to align at the bottom 1</div>
      <div id="alignBottom2">Text to align at the bottom 2</div>
    </div>
    <div class="col-sm-12">footer</div>
  </div>
</div>

CSS flexbox可以用几行代码以多种方式对齐容器内的内容。这可能对您有用。

#TotContainer {
  height: 900px;
}

#container {
  max-height: 90%
}

.col-sm-6 {
  width: 50%;
  float: left;
  height: 100%;
  padding: 10px;
}
.col-sm-6:nth-child(2){
 /* adding this */
  display: flex;
  flex-direction: column;
  justify-content: flex-end;
  /* adding some height to the container for better visibility od effect */
  height: 80px;
}

.col-sm-12 {
  width: 100%;
  float: left;
  background: yellow;
}

* {
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
}

<div id="TotContainer">
  <div id="container">
    <div class="col-sm-6" style="background:blue;">XXXXXX</div>
    <div class="col-sm-6" style="background:red;">
      <div id="alignBottom1">Text to align at the bottom 1</div>
      <div id="alignBottom2">Text to align at the bottom 2</div>
    </div>
    <div class="col-sm-12">footer</div>
  </div>
</div>
