感谢

您的HTML将看起来像这样：

 < div id =panel> 
< div class =wrapper> 
< div id =bottom> 
< div class =update> 
 a 
< / div> 
< / div> 
< / div> 
< / div> 
  

和您的CSS：

  #panel {
 width：21.25％; 
 height：100％; 
 background-color：＃0794ea; 
 float：left; 
 padding：0 1.5％; 
 box-sizing：border-box; 
} 
 
 .update {
 width：100％; 
 background-color：＃006699; 
 text-align：center; 
 height：56px; 
颜色：白色
} 
 
 .wrapper {
 position：relative; 
 height：100％; 
} 
 
 #bottom {
 position：absolute; 
 bottom：20px; 
 left：0; 
 width：100％; 
 background：yellow; 
}

解决方案

You can fix the issue using a wrapper

Your HTML will look something along these lines:

<div id="panel">
    <div class="wrapper">
        <div id="bottom">
            <div class="update">
                a          
            </div>
        </div>    
    </div>
</div>

And your CSS:

#panel {
    width: 21.25%;
    height: 100%;
    background-color: #0794ea;
    float: left;
    padding: 0 1.5%;
    box-sizing: border-box;
}

.update {
    width: 100%;
    background-color: #006699;
    text-align: center;
    height: 56px;
    color: white;
}

.wrapper {
    position: relative;
    height: 100%;
}

#bottom {
    position: absolute;
    bottom: 20px;
    left: 0;
    width: 100%;
    background: yellow;
}
