XHTML tags Different browser technologies targets
different devices Therefore - by combining HTML and XML,
and their strengths, we got a markup language that is useful now and in the future - XHTML.
XHTML pages can be read by all XML enabled devices
XHTML tags XHTML is a combination of HTML and XML
(eXtensible Markup Language). XHTML consists of all the elements in HTML
4.01 combined with the syntax of XML. XML is a markup language where
everything has to be marked up correctly, which results in "well-formed" documents.
“Safe” XHTML example
<?xml version= "1.0" encoding= "utf-8" ?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd" ><html xmlns= "http://www.w3.org/1999/xhtml1" xml:lang= "en-ca" lang= "en-ca" ><head><title> ... </title><meta http-equiv= "content-type" content= "text/html;charset=utf-8" /></head><body>.....</body></html>
spacebefore slash
XHTML tags Three types of XHTML pages, they are:
Strict: Use with CSS
Transitional: The Transitional DTD includes presentation attributes and elements that W3C expects to move to a style sheet. Use this when you need to use HTML's presentational features because your readers don't have browsers that
support Cascading Style Sheets (CSS) Frameset: documents with frames
Add the <!doctype> tag <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
How to write properly XHTML tags
Use all lower case Attributes goes in quotes Close all tags Always nest tags properly
