XHTML

Here are all the XHTML Strict tags in alphabetical order. Once per day I will write about one of these tags starting with the a tag and working my way down to the var tag. I will describe each tag, tell what it does, give my two cents on it and show some examples. But first you might ask, "What is XHTML and how is it different than HTML. Is it better? Why or why not?" I will answer those questions right now. XHTML stands for Extensible HyperText Markup Language. From Wikipedia:

Whereas HTML is an application of Standard Generalized Markup Language (SGML), a very flexible markup language, XHTML is an application of XML, a more restrictive subset of SGML. Because they need to be well-formed, true XHTML documents allow for automated processing to be performed using standard XML tools—unlike HTML, which requires a relatively complex, lenient, and generally custom parser. XHTML can be thought of as the intersection of HTML and XML in many respects, since it is a reformulation of HTML in XML. XHTML 1.0 became a World Wide Web Consortium (W3C) Recommendation on January 26, 2000. XHTML 1.1 became a W3C recommendation on May 31, 2001.

Here are the basic of XHTML

1. Declare a DOCTYPE
2. Declare an XML namespace
3. Declare your content type
4. Close every tag, enclosing or non-enclosing
5. All tags must be nested correctly
6. Inline tags can't contain block level tags
7. Write tags in lowercase
8. Attributes must have values and must be quoted
9. Use encoded equivalents for left brace and ampersand
