我对z-index有点帮助...
我正在玩代码，需要我的id =“hidebar”才能坐在“content”和“content-inner”div之上。对不起，如果这看起来很基本，但我很挣= D

我的CSS结构文件：

body
{
    margin: 0; 
    padding: 0;
    height:100%;
    width:100%;
    background-color: #FFF;
    z-index:-1;
} 
#content
{
    width: 100%;
    height: 640px;
    background-color:#060;
    position:relative;
    z-index:-1;
}
#content-inner
{
    width: 960px;
    height: 640px;
    background-color:#666;
    margin-left:auto;
    margin-right:auto;
    position:relative;
    z-index:-1;
}

#hidebar
{
    width: 100%;
    height: 50px;
    background-color:#0FF;
    position:relative;
    z-index:2;
}



#navbar
{
    width: 100%;
    height: 257px;
    background-color:#F00;
    position:relative;
}
#navbar-inner
{
    width: 960px;
    height: 257px;
    background-color:#666;
    margin-left:auto;
    margin-right:auto;
    position:relative;
}

#footer
{
    width: 100%;
    height: 181px;
    background-image:url(images/gray-pixel.png);
    position:relative;  
}
#footer-inner
{
    width: 960px;
    height: 181px;
    background-color:#666;
    margin-left:auto;
    margin-right:auto;
    position:relative;
}
#footer-small
{
    width:230px;
    float:left;
    height:100%;
    background-color:#999;
    position:relative;
}
#footer-large
{
    width:500px;
    float:left;
    height:100%;
    background-color:#CCC;
    position:relative;
}
#colour-bar
{
    width: 100%;
    height: 13px;
    background-color:#639;
    position:relative;
}

如果您希望#hidebar位于#contents和#content-inner之上，则只需重新定位#hidebar。

<div id="content">
        <div id="content-inner">
            <div id="hidebar">

            </div>
            <a href="index.html">
                <img src="images/logo.jpg" />
            </a>
        </div>
    </div>

z-index没有应该分层
