Universal compliance with W3C standards means understanding the rules of mark up languages in the web development process. This is in order to render a perfect compatible web design to the browsers and hence create a uniform browser rendering on the WWW website viewers.
Created in early nineties HTML as a web development language overtook older SGML or standard general mark up language. SGML was used to standardise management, exchange and publish all electronic documents on the Internet.
Since the inception HTML pages have been upgraded a number of times constantly as follows:
1995 – HTML 2.0
1997 – HTML 3.2
1999 – HTML 4
2000 – XHTML 1.0
2001 – XHTML 1.1
Most commonly used DTDs are HTML 4.01 and XHTM 1.0 although older versions are still functional. The common DTDs are as follows:
HTML 4.01 Strict
HTML 4.01 Transitional
HTML 4.01 Frameset
XHTMl 1.0 Strict
XHTML 1.0 Transitional
XHTML 1.0 Frameset
XHTML 1.1 DTD
The gradual upgradtion lead W3C standard to recommend the removal of presentation orientation tags to using CSS or cascading style sheet. XHTML specification built on HTML will eventually lead to compatiblity with eXtensive Mark Up Language i.e. XML in the future.
