忽略100%的子div高度

Question

我正在使用peter的一个很好的例子，一个100%高度的div和一个粘性的页脚(HERE)。我省略了页脚部分，我没有用到它。

然而，每当我使用一个子div并尝试做同样的事情时，它都不起作用。我想要一个子div也接受它父级高度的100%。下面是CSS：

<style>


    html,body {
        margin:0;
        padding:0;
        height:100%; /* needed for container min-height */
        background:gray;

        font-family:arial,sans-serif;
        font-size:small;
        color:#666;
    }



    div#container {
        position:relative; /* needed for footer positioning*/
        margin:0 auto; /* center, not in IE5 */
        width:750px;
        background:#f0f0f0;

        height:auto !important; /* real browsers */
        height:100%; /* IE6: treaded as min-height*/

        min-height:100%; /* real browsers */
    }

    div#header {
        padding:1em;
        background:#ddd url("../csslayout.gif") 98% 10px no-repeat;
        border-bottom:6px double gray;
    }


    div#content {
        padding:1em 1em 5em; /* bottom padding for footer */
        position:relative; /* needed for footer positioning*/
        margin:0 auto; /* center, not in IE5 */

        height:auto !important; /* real browsers */
        height:100%; /* IE6: treaded as min-height*/

        min-height:100%; /* real browsers */            
    }
    div#content_subdiv{
        padding:1em 1em 5em; /* bottom padding for footer */
        background:#999;
        height:100%;

        color:#fff;
    }


</style>

下面是我的HTML代码：

<div id="container"> 

    <div id="header"> 
        <h1>CSS layout: 100% height with header and footer</h1> 
        <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam eget massa dolor, rhoncus tempor nunc. Donec tempor odio eget purus vehicula auctor. </p> 
    </div> 

    <div id="content"> 

        <p> 
    Aenean quam mauris, iaculis non aliquet quis, facilisis sed turpis. Cras id erat velit, nec bibendum erat. Vivamus feugiat purus vitae velit dictum in vestibulum ante tristique. Vestibulum ut massa vel justo eleifend consectetur eget ut nisi. Phasellus ut diam nulla. Suspendisse potenti. Praesent blandit gravida facilisis. Donec elementum faucibus gravida. Nullam nec enim velit, ac scelerisque justo. Pellentesque lacus metus, adipiscing nec congue a, volutpat sollicitudin eros. Donec tortor leo, tempor non viverra at, molestie sed dui. Nullam ipsum purus, tempus elementum tincidunt id, iaculis at lectus. Vestibulum viverra mi in mauris ultrices sollicitudin
        </p> 
        <div id="content_subdiv"> this sub div not stretching to 100%; <br /> this sub div not stretching to 100%; <br /> this sub div not stretching to 100%; <br /> this sub div not stretching to 100%; <br /> this sub div not stretching to 100%; <br /></div>
    </div> 

</div> 

Answer 1

只能将min-height:100%应用于body的第一个元素。

将头文件放在content div中，或者创建一个min-height:100% wrapper div。

Answer 2

然后试试下面的代码：

html,body {
    margin:0;
    padding:0;
    height:100%; /* needed for container min-height */
    background:gray ;
    font-family:arial,sans-serif;
    font-size:small;
    color:#666;
}



div#container {
    position:relative; /* needed for footer positioning*/
    margin:0 auto; /* center, not in IE5 */
    width:750px;
    background:#f0f0f0;

    height:auto !important; /* real browsers */
    height:100%; /* IE6: treaded as min-height*/

    min-height:100%; /* real browsers */
}

div#header {
    padding:1em;
    background:#ddd url("../csslayout.gif") 98% 10px no-repeat;
    border-bottom:6px double gray;
}


div#content {
    padding:1em 1em 5em; /* bottom padding for footer */
    position:relative; /* needed for footer positioning*/
    margin:0 auto; /* center, not in IE5 */

    height:auto !important; /* real browsers */
    height:100%; /* IE6: treaded as min-height*/

    min-height:100%; /* real browsers */            
}
div#content_subdiv{
    padding:1em 1em 5em; /* bottom padding for footer */
    background:#999;
   color:#fff;    }  
< div id="header "> 
    < h1 >CSS layout: 100% height with header and footer</ h1 > 
    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam eget massa dolor, rhoncus tempor nunc. Donec tempor odio eget purus vehicula auctor. </p> 
</div> 

<div id="content"> 

    <p> 
Aenean quam mauris, iaculis non aliquet quis, facilisis sed turpis. Cras id erat velit, nec bibendum erat. Vivamus feugiat purus vitae velit dictum in vestibulum ante tristique. Vestibulum ut massa vel justo eleifend consectetur eget ut nisi. Phasellus ut diam nulla. Suspendisse potenti. Praesent blandit gravida facilisis. Donec elementum faucibus gravida. Nullam nec enim velit, ac scelerisque justo. Pellentesque lacus metus, adipiscing nec congue a, volutpat sollicitudin eros. Donec tortor leo, tempor non viverra at, molestie sed dui. Nullam ipsum purus, tempus elementum tincidunt id, iaculis at lectus. Vestibulum viverra mi in mauris ultrices sollicitudin
    </p> 

</div> <div id="content_subdiv"> this sub div not stretching to 100%; <br /> this sub div not stretching to 100%; <br /> this sub div not stretching to 100%; <br /> this sub div not stretching to 100%; <br /> this sub div not stretching to 100%; <br /></div>

好的，我在问题中没有看到你的#content_subdiv的CSS ...？
