The first version of HTML was written by Tim Berners-Lee in 1993. Since then, there have been many different versions of HTML. The most widely used version throughout the 2000's was HTML 4.01, which became an official standard in December 1999.

HTML was one of the first web-development languages i have learned in 1993 with version 1.2
I am endorsed through an assessment on LinkedIn (under the Skills & Endorsements section) with over 20 years of actively writing HTML software. 

Some of my work can be found in the PROJECTS section of this site.
