網站常常以多列顯示內容(就像雜志和報紙)。
注釋:<div> 元素常用作布局工具,因為能夠輕松地通過 CSS 對其進行定位。
這個例子使用了四個 <div> 元素來創建多列布局:
<body><div id="header"><h1>City Gallery</h1></div><div id="nav">London<br>Paris<br>Tokyo<br></div><div id="section"><h1>London</h1><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.</p></div><div id="footer">Copyright W3School.com.cn</div></body>

<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>
HTML5 提供的新語義元素定義了網頁的不同部分:
header | 定義文檔或節的頁眉 |
nav | 定義導航鏈接的容器 |
section | 定義文檔中的節 |
article | 定義獨立的自包含文章 |
aside | 定義內容之外的內容(比如側欄) |
footer | 定義文檔或節的頁腳 |
details | 定義額外的細節 |
summary | 定義 details 元素的標題 |
這個例子使用 <header>, <nav>, <section>, 以及 <footer> 來創建多列布局:
<body><header><h1>City Gallery</h1></header><nav>London<br>Paris<br>Tokyo<br></nav><section><h1>London</h1><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.</p></section><footer>Copyright W3School.com.cn</footer></body>

<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; }
注釋:<table> 元素不是作為布局工具而設計的。
<table> 元素的作用是顯示表格化的數據。
使用 <table> 元素能夠取得布局效果,因為能夠通過 CSS 設置表格元素的樣式:
<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>
