Short for Extensible HyperText Markup
Language, a hybrid between
HTML and
XML specifically
designed for Net device displays.
XHTML is a markup language written in XML; therefore, it is an XML application.
XHTML uses three XML namespaces (used to qualify element and
attributes names by associating them with namespaces identified by
URI references.
Namespaces prevent identically custom-named tags that may be used in
different XML documents from being read the same way), which correspond
to three XHTML 1.0 DTDs:
Strict, Transitional, and Frameset.
XHTML markup must conform to the markup standards defined in the DTD.
XHTML is a reformulation of HTML 4.01 in XML, and can be put to immediate
use with existing browsers by following a few simple guidelines.
To prepare for the future, this web site has been completely written in XHTML 1.0.
