当内容本身没有时，我在让我的内容容器 div 正确扩展到页面底部时遇到了一些麻烦。如果内容很短并且没有填满页面，则容器仍会超出页面底部。

这是结构：

<div id="container">

    <div id="logo"></div>

    <div class="clear"></div>



<div class="spacer"></div>

<div class="content">


        <div class="post">

        <div class="right"></div>
    </div>


    <div id="centerit">/div>    
</div></body></html>

这是CSS：

body{background:url(bg.jpg);font-family:verdana, helvetica, sans-serif;font-size:12px;line-height:18px;color:#b3b3b3;height:100%;min-height:100%;}

    a{color:#fff;text-decoration:none;font-weight:bold;outline:none;}

    /* a:hover{color:#289bc6;} */

html { height: 100%; }
    #container{width:1200px;margin:auto;height:100%;position:relative;}

    #logo{font-size:18px;line-height:37px;color:#222;float:left;display:block;clear:both;}

    #nav{margin:auto;background:#000;padding;2px 800px 0px 0px;width:800px;}

调整并将其添加到组合中：

html { height: 100%; min-height: 100; /* min-height is for FF */ }
#content { height: -webkit-calc-height(100% - 37px); } /* be sure to add all vendor prefixes, also change 37px to the correct height of elements above the #content */
