headhtml介绍

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

●HTML 4.01 Frameset

●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

  1. <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

  1. <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

  1. <html lang="zh-cmn-Hans">

  繁体中文


XML/HTML Code复制内容到剪贴板

  1. <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

  1. <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

  1. <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

  1. <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
