{
margin
:0;
padding
:0;
}
body
{
margin
:10px;
}
#header
{
border
:1px solid black;
width
:600px;
height
:60px;
margin
:0 auto;
margin-bottom
:10px;
}
#header h1
{
height
:60px;
line-height
:60px;
font-size
:16px;
text-align
:center;
}
#body
{
width
:600px;
margin
:0 auto;
}
#navl
{
border
:1px solid black;
width
:150px;
height
:500px;
float
:left;
margin-bottom
:10px;
background
:lightcyan;
}
#main
{
border
:1px solid black;
width
:294px;/*边框也算一个像素*/
height
:500px;
float
:left;
margin-bottom
:10px;
background
:lightblue;
}
#navr
{
border
:1px solid black;
width
:150px;
height
:500px;
float
:right;
margin-bottom
:10px;
background
:lightyellow;
}
#footer
{
border
:1px solid black;
width
:600px;
height
:60px;
line-height
:60px;
margin
:0 auto;
text-align
:center;
clear
:both;
}

效果如下:

这种布局的好处是:由于固定了div的宽和高,所有改变浏览器窗口的大小不是影响到div的显示。
