HTML 布局
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,因为能够轻松地通过 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
<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 www.sucainiu.com </div> </body>
CSS:
<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>
使用 HTML5 的网站布局
HTML5 提供的新语义元素定义了网页的不同部分:
HTML5 语义元素
header | 定义文档或节的页眉 |
nav | 定义导航链接的容器 |
section | 定义文档中的节 |
article | 定义独立的自包含文章 |
aside | 定义内容之外的内容(比如侧栏) |
footer | 定义文档或节的页脚 |
details | 定义额外的细节 |
summary | 定义 details 元素的标题 |
这个例子使用 <header>, <nav>, <section>, 以及 <footer> 来创建多列布局:
实例
<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 www.sucainiu.com </footer> </body>
CSS
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; }
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>
CSS
<style> table.lamp { width:100%; border:1px solid #d4d4d4; } table.lamp th, td { padding:10px; } table.lamp td { width:40px; } </style>
