分享关于CSS样式排版问题
帮我看一下这代码有问题吗：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<style>
#container{
width:975px;
}
#header{

background:url(./images/index_01.gif);
}
#nav{

}
#navl{

height:118px;
margin:0px;

}
#navm{
width:400px;
height:118px;
margin:0px;
float:left;
background:url(./images/index_03.gif);
}
#navr{
width:289px;
height:118px;
margin:0px;
float:left;
background:url(./images/index_04.gif);
}
</style>
</head>
<body>
<div id="container">
<div id="header"></div>
<div id="nav">
<dir id="navl"></dir>
<dir id="navm"></dir>
<dir id="navr"></dir>
</div>
</div>
</div>
</body>
</html>
显示的结果为什么会这样
这三张图片尺寸都没错，为什么都会多出一一边，导致并排不下多出一行？

在三个图片DIV样式里加 padding:0px; 用FIREFOX 的firebug布局看下就知道了嘛
