XHTML files first use XML's syntax to life, and then use HTML tags to design web pages.
- Document Main Body ->
EX110.1 </ title> </ head> <body> <center> <h2 stytle = "color: red"> XHTML & IE 5.5 </ h2 > <h1> stytle = "color: blue"> asdfasdfasdf </ h1> </ center> </ body> </ tml></p>
<p>The declaration area: XHTML file is the area of XML, so you need to declare it with <? XML Version = "1.0"?>. The default font of the system is UTF-8 and UTF-16. If you want to use other fonts, you must specify in the declaration area. For example: <? XML Version = "1.0" encoding = "gb2312"?> <! Doctype html public "- // w3c // DTD XHTML 1.0 stric // en" "http://www.w3c.org/tr/ XHTML / DTD / XHTML1-STRICT.DTD "> <html xmlns =" http://www.w3c.org/1999/xhtml "> <head> <title> EX110.1 </ title> </ head> <body > <center> <h2 stytle = "color: red"> XHTML & IE 5.5 </ h2> <h1> stytle = "color: blue"> asdfasdfasdf </ h1> </ center> </ body> </ tml></p>
<p>If you just display the XHTML file content on your browser, you can omit <XML>, omitted the declaration of XML -> <! Doctype html public "- // w3c // DTD XHTML 1.0 Strict // en" " http://www.w3c.org/tr/xhtml/dtd/xhtml1-strict.dtd"><HTML XMLns = "http://www.w3c.org/1999/xhtml"> <head> <title> EX110 . 1 </ title> </ head> <body> <center> <h2 stytle = "color: red"> XHTML & IE 5.5 </ h2> <h1> stytle = "color: blue"> asdfasdfasdf </ h1> </ center> </ body> </ truml> file format definition: XML custom tag must be defined by <! docty>, or store tag properties and related information in * .dtd file, use < !
