How to place the footer tag at the bottom of the page

This time I will show you how to place the footer tag at the bottom of the page. What are the precautions? Here are the actual cases, let's take a look.

Requirements: Sometimes, when the page content is short and cannot support the height of the browser, but you want the footer to be at the lowest end of the window.

Idea: The minimum height of the footer's parent layer is 100%. The footer is set to be absolutely bottom (bottom: 0) relative to the position of the parent layer. The height of the footer must be reserved in the parent layer.

html code:

<!-- 父层 -->     
<div id="wapper">     
    <!-- 主要内容 -->     
    <div id="main-content">     
    </div>     
    <!-- 页脚 -->     
    <div id="footer">     
    </div>     
</div>

CSS is as follows:

#wapper{     
    position: relative;   /*重要！保证footer是相对于wapper位置绝对*/     
    height: auto;          /* 保证页面能撑开浏览器高度时显示正常*/     
    min-height: 100%  /* IE6不支持，IE6要单独配置*/     
}     
#footer{     
   position: absolute;  bottombottom: 0; /* 关键 */     
   left:0; /* IE下一定要记得 */     
   height: 60px;         /* footer的高度一定要是固定值*/     
}     
#main-content{     
   padding-bottom: 60px; /*重要！给footer预留的空间*/     
}

At this time, other browsers can display normally, but IE 6 needs to be processed separately:

<!--[if IE 6]->     
<style>     
#wapper{height:100%;} /* IE在高度不够时会自动撑开层*/     
</style>     
<![endif]-->
