網(wǎng)站常常以多列顯示內(nèi)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(jìn)行定位。
這個例子使用了四個 <div> 元素來創(chuàng)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 365jz.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(wǎng)頁的不同部分:
header | 定義文檔或節(jié)的頁眉 |
nav | 定義導(dǎo)航鏈接的容器 |
section | 定義文檔中的節(jié) |
article | 定義獨立的自包含文章 |
aside | 定義內(nèi)容之外的內(nèi)容(比如側(cè)欄) |
footer | 定義文檔或節(jié)的頁腳 |
details | 定義額外的細(xì)節(jié) |
summary | 定義 details 元素的標(biāo)題 |
這個例子使用 <header>, <nav>, <section>, 以及 <footer> 來創(chuàng)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 365jz.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(shè)計的。
<table> 元素的作用是顯示表格化的數(shù)據(jù)。
使用 <table> 元素能夠取得布局效果,因為能夠通過 CSS 設(shè)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>
