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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | < 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 > |
CSS:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | < 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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | < 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 > |
CSS:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | < 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; } |
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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | < 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
1 2 3 4 5 6 7 8 9 10 11 12 | < style > table.lamp { width:100%; border:1px solid #d4d4d4; } table.lamp th, td { padding:10px; } table.lamp td { width:40px; } </ style > |
