我有三个主要的 div，它们header是main-container和footer。div的CSS是

#main_container
{
    width:950px;
    margin:0 auto;

}
#header
{
    background:#f4f8f9;
}
#footer
{
    clear:both;
    background:#355e95;
    height:40px;
    color:#fff; 
    font-size:13px;
    font-family: "Franklin Gothic Medium", "Franklin Gothic", "ITC Franklin Gothic", Arial, sans-serif;
    text-align:center;
    padding-top:10px;
    padding-bottom:10px;
}

现在，在索引页面中，没有左右浮动，因此页脚位于底部。但是在随后的页面中，有很多浮动，现在页脚在上面main-container！为什么会发生这种情况？我已经在divfloating之前清除了footer

<div class="clr"></div> 
    <div id="footer">
         &copy;2010 Sri Sai Group
         <div class="fbtm">
            Powered,Maintained and Designed By <a href="http://7sisters.in" target="_blank">7sisters.in</a>
         </div>
    </div>

注意当我添加overflow:auto;页面时是这样的！ 编辑的 CSS 页面

我的页面之一的完整 HTML：

<body>
    <div id="header">
        <div class="htop">
            <div class="phn">Ph +0361-26699811</div>

看起来你需要做的是在页脚之前关闭你的 maincontent div，它在那里缺少一个这样做（如果你相信你已经拥有它不是）。

            <div>
            <input id="send" name="send" type="submit" value="Send" />
        </div>
    </form>
    </div>
</div></div>



<div class="clr"></div> 
<div id="footer">
     &copy;2010 Sri Sai Group
     <div class="fbtm">
        Powered,Maintained and Designed By <a href="http://7sisters.in"
   target="_blank">7sisters.in</a>
     </div>

另外，也许可以考虑将 maincontent 宽度设为 % 以阻止它在某些浏览器上扩展得太远。

#main_container
{
width:100%;
margin:0 auto;

}

您应该添加overflow:auto到您的#main_containercss 中，以便它根据其子元素的大小增加高度。然后#footer将直接在#main_container这意味着所有内容之后。

#main_container
{
    width:950px;
    margin:0 auto;
    overflow: auto; /* add this */
}
