本篇以一丝的文章为基础，进行扩展总结介绍常用的 head 中各个标签、元素的意义以及使用场景
HTML head 头部分的标签、元素有很多，涉及到浏览器对网页的渲染，SEO 等等，而各个浏览器内核以及各个国内浏览器厂商都有些自己的标签元素,这就造成了很多差异性。移动互联网时代，head 头部结构，移动端的 meta 元素，显得更为重要。了解每个标签的意义，写出满足自己需求的 head 头标签，是本文的目的。本篇以一丝的文章为基础，进行扩展总结介绍常用的 head 中各个标签、元素的意义以及使用场景。
DOCTYPE
DOCTYPE(Document Type)，该声明位于文档中最前面的位置，处于 html 标签之前，此标签告知浏览器文档使用哪种 HTML 或者 XHTML 规范。
DTD(Document Type Definition) 声明以 开始，不区分大小写，前面没有任何内容，如果有其他内容(空格除外)会使浏览器在 IE 下开启怪异模式(quirks mode)渲染网页。公共 DTD，名称格式为注册//组织//类型 标签//语言,注册指组织是否由国际标准化组织(ISO)注册，+表示是，-表示不是。组织即组织名称，如：W3C。类型一般是 DTD。标签是指定公开文本描述，即对所引用的公开文本的唯一描述性名称，后面可附带版本号。最后语言是 DTD 语言的 ISO 639 语言标识符，如：EN 表示英文，ZH 表示中文。XHTML 1.0 可声明三种 DTD 类型。分别表示严格版本，过渡版本，以及基于框架的 HTML 文档。
●HTML 4.01 strict

●HTML 4.01 Transitional

●最新 HTML5 推出更加简洁的书写，它向前向后兼容，推荐使用。

在 HTML中 doctype 有两个主要目的。
●对文档进行有效性验证。
它告诉用户代理和校验器这个文档是按照什么 DTD 写的。这个动作是被动的，每次页面加载时，浏览器并不会下载 DTD 并检查合法性，只有当手动校验页面时才启用。
●决定浏览器的呈现模式
对于实际操作，通知浏览器读取文档时用哪种解析算法。如果没有写，则浏览器则根据自身的规则对代码进行解析，可能会严重影响 html 排版布局。浏览器有三种方式解析 HTML 文档。
●非怪异（标准）模式
●怪异模式
●部分怪异（近乎标准）模式 关于IE浏览器的文档模式，浏览器模式，严格模式，怪异模式，DOCTYPE 标签，可详细阅读模式？标准！的内容。
charset
声明文档使用的字符编码，
XML/HTML Code复制内容到剪贴板
<meta charset="utf-8">
html5 之前网页中会这样写：
XML/HTML Code复制内容到剪贴板
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
这两个是等效的，具体可移步阅读： vs ，所以建议使用较短的，易于记忆。
lang属性
简体中文
XML/HTML Code复制内容到剪贴板
<html lang="zh-cmn-Hans">
繁体中文
XML/HTML Code复制内容到剪贴板
<html lang="zh-cmn-Hant">
为什么 lang="zh-cmn-Hans" 而不是我们通常写的 lang="zh-CN" 呢，请移步阅读: 页头部的声明应该是用 lang="zh" 还是 lang="zh-cn"。
优先使用 IE 最新版本和 Chrome
XML/HTML Code复制内容到剪贴板
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
360 使用Google Chrome Frame
XML/HTML Code复制内容到剪贴板
<meta name="renderer" content="webkit">
360 浏览器就会在读取到这个标签后，立即切换对应的极速核。 另外为了保险起见再加入
XML/HTML Code复制内容到剪贴板
<meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1">
这样写可以达到的效果是如果安装了 Google Chrome Frame，则使用 GCF 来渲染页面，如果没有安装 GCF，则使用最高版本的 IE 内核进行渲染。

百度禁止转码
通过百度手机打开网页时，百度可能会对你的网页进行转码，脱下你的衣服，往你的身上贴狗皮膏药的广告，为此可在 head 内添加
