一般有几种DOCTYPE文档类型

IE5.5 发明了文档模式的概念 doctype

最初：混杂模式 + 标准模式
后来：+准标准模式

混杂模式 标准模式 准标准模式
省略doctype Transitional Frameset
  • HTML 4.01 规定了三种文档类型：Strict、Transitional 以及 Frameset。
  • XHTML 1.0 规定了三种 XML 文档类型：Strict、Transitional 以及 Frameset。
  • Standards （标准）模式（也就是严格呈现模式）用于呈现遵循最新标准的网页，
  • Quirks（包容）模式（也就是松散呈现模式或者兼容模式）用于呈现为传统浏览器而设计的网页。
