Why is height:auto not working on 2 floating elements?
提问by Sreeja Das
The div#inner1and div#inner2are inside the div#outer, but still the height of div#outershows as 0px with height:auto.
该div#inner1和div#inner2是内部的div#outer,但仍然高度div#outer显示为0像素带height:auto。
How do I get the height of the child elements for the outer div?
如何获取外部 div 的子元素的高度?
This is my code:
这是我的代码:
#outer {
  width: 300px;
  height: auto;
  background: #ccc;
}
#inner1 {
  float: left;
  width: 100px;
  height: 100px;
  background: #f00;
}
#inner2 {
  float: left;
  width: 100px;
  height: 100px;
  background: #0f0;
}<div id="outer">
  <div id="inner1"></div>
  <div id="inner2"></div>
</div>采纳答案by Sreeja Das
Float the outer div. that will cover your all height, whatever the inner divs holding heights. But if you will provide your inner div float property. then i will suggest you to use the hack clearfix..
浮动外部div。这将覆盖您的所有高度,无论内部 div 保持高度。但是,如果您提供内部 div 浮动属性。那么我会建议你使用hack clearfix ..
    /* Assuming this HTML structure:
    <div class="clear">
        <div class="floated"></div>
        <div class="floated"></div>
        <div class="floated"></div>
    </div>
*/
.clear:before, .clear:after {
    content: "##代码##20";
    display: block;
    height: 0;
    overflow: hidden;
}
.clear:after {
    clear: both;
}
try this it will sure work
试试这个它肯定会工作
