网站常常以多列显示内容（就像杂志和报纸）。
使用<div>元素的HTML布局
注释：<div>元素常用作布局工具，因为能够轻松通过CSS对其进行定位。
这个例子使用了四个<div>元素来创建多列布局
实例：
<!DOCTYPE html>
<html>
<head>
<style>
#header {
background-color:black;
color:white;
text-align:center;
padding:5px;
}
#nav {
line-height:30px;
background-color:#eeeeee;
height:300px;
width:100px;
float:left;
padding:5px;
}
#section {
width:350px;
float:left;
padding:10px;
}
#footer {
background-color:black;
color:white;
clear:both;
text-align:center;
padding:5px;
}
</style>
</head>
<body>
<div id="header">
<h1>City Gallery</h1>
</div>
<div id="nav">
London<br>
Paris<br>
Tokyo<br>
</div>
<div id="section">
<h2>London</h2>
<p>
London is the capital city of England. It is the most populous city in the United Kingdom,
with a metropolitan area of over 13 million inhabitants.
</p>
<p>
Standing on the River Thames, London has been a major settlement for two millennia,
its history going back to its founding by the Romans, who named it Londinium.

使用表格的HTML布局
注释：<table>元素不是作为布局工具而设计的。
<table>元素的作用是显示表格化的数据。
使用<table>元素能够取得布局的效果，因为能够通过CSS设置表格元素的样式。
实例：
<body>
<table class="lamp">
<tr>
<th>
<img src="/images/lamp.jpg" alt="Note" style="height:32px;width:32px">
</th>
<td>
The table element was not designed to be a layout tool.
</td>
</tr>
</table>
</body>
<style>
table.lamp {
width:100%;
border:1px solid #d4d4d4;
}
table.lamp th, td {
padding:10px;
}
table.lamp td {
width:40px;
}
</style>
