后缀为html、htm与shtml文件的区别_html/css_WEB-ITnose
1、.htm与.html没有本质上的区别,都是超文本标记语言(HyperTextMark-upLanguage),是WWW的描述语言,表示的是同一种文件,只是适用于不同的环境之下。
2、DOS仅能识别8+3的文件名,所以*.htm的命名方法可以被DOS识别,而*.html的文件命名方式不能被识别。
3、在UNIX系统中,网页必须使用.html扩展名,如果是htm,在浏览器中打开时则出现源代码;Windows中支持两种扩展名。也可以说,htm和html是Windows和UNIX对抗的产物。
4、如果在网页中同时存在index.html与index.htm,这时浏览器将先解释index.html。
5、.shtml是一种用于SSI(Server Side Include,服务器端包含)技术的文件,是WEB在服务器提供的一种功能,并且在服务器端执行。一般说来,要完成较复杂的任务(如:聊天室/留言本等),必须设计专门的CGI或ASP程序;但是如果只是想给网页加上简单的功能(如:显示一篇文档,web服务器环境变量,关于该文档的更新日期/大小等),则只要SSI就可以完成了。
