三、超文本标记语言(HTML) 标准通用化标记语言(SGML,即Standard General-ized Markup Language)是一种元语言,即用来描述标记语言的语言。它是一种国际标准,发布于1986年。而超文本标记语言(HTML,即Hyper Text Markup Lan-guage)是SGML的一种应用,它继承了SGML的许多特征。HTML语法是用SGML文档类型定义而成。 HTML拥有一套规范Web文档格式的规则。利用HTML,就可以创建Web文档。用HTML创建的Web文档可以被运行在不同硬件和不同操作系统上的应用程序(如浏览器)所识别,电就是说,HTML文档是与系统平台和应用程序无关的。
Third, the Hypertext Markup Language (HTML) standard Generalized Markup Language (SGML, or Standard Generalized ized Markup Language) is a meta language, that is, used to describe the language of the markup language. It is an international standard, released in 1986. Hypertext Markup Language (HTML), or Hyper Text Markup Lan-guage, is an application of SGML that inherits many of SGML’s features. HTML syntax is defined by the SGML document type. HTML has a set of rules that govern the format of web documents. With HTML, you can create web documents. Web documents created with HTML can be recognized by applications (such as browsers) that run on different hardware and operating systems, which means that the HTML document is independent of the system platform and application.
