1，看一下头部
先看一下xhtml的写法
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
- <html xmlns="http://www.w3.org/1999/xhtml">
- <head>
- <title>title</title>
- <meta name="description" content="description"/>
- <link rel="stylesheet" type="text/css" href="/c3.css" />
- <meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
- <meta http-equiv="Content-Language" content="zh-cn" />
- <meta name="robots" content="all" />
- <meta name="author" content="lunanzuche.com.cn" />
- <meta name="Copyright" content="Copyright www.lunanzuche.com All Rights Reserved." />
- <meta name="MSSmartTagsPreventParsing" content="true" />
- <meta http-equiv="p_w_picpathtoolbar" content="false" />
看一下html5
- <!DOCTYPE html>
- <html lang="en-US">
- <head>
- <meta charset="utf-8" />
- <meta HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=utf-8">
- <title>Goldman Sachs</title>
显著区别在于:
- <meta charset="utf-8" />
- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
- <html xmlns="http://www.w3.org/1999/xhtml">
与
- <!DOCTYPE html>
- <html lang="en-US">
- 当然 lang可以不写
- <meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
换成了:
