HTML was first defined by Tim Berners-Lee in 1991 and has evolved through several versions. HTML5 and CSS3 are the next generation standards that will enhance the richness and interactivity of web content. HTML5 introduces new semantic tags and APIs for multimedia, geolocation, and offline storage. CSS3 includes features for rounded corners, drop shadows, columns, animations, and media queries for responsive design. While legacy browsers present challenges, HTML5 and CSS3 will improve the functionality of the mobile web and make the interface of the web comparable to native applications.

2. HTML Pre-History General Markup Language (GML) was developed at IBM in the 1960's by Charles F. Goldfarb :h1.Chapter 1: Introduction :p.GML supported hierarchical containers, such as :ol :li.Ordered lists (like this one), :li.Unordered lists, and :li.Definition lists :eol. as well as simple structures. :p.Markup minimization (later generalized and formalized in SGML), allowed the end-tags to be omitted for the "h1" and "p" elements. http://www.sgmlsource.com/history/roots.htm

3. HTML Pre-History Standard Generalized Markup Language (SGML) was derived from GML in the 1980's. SGML was the pre-cursor to both HTML and XML. SGML defined the user of angle brackets for tags. <example>

5. HTML 2, 3, and 4 HTML 2 added many of the attributes we know today such as images, forms, input. HTML 3 added new tags that had been part of minor revisions. HTML 4 extended the number of tags. Currently most HTML is 4.01

7. CSS History CSS 1 was proposed in 1995 as a way to style documents. It contained descriptions for font, background and other style tags. CSS 2 is the version we currently use added positioning and other elements.

8. Web Usability Then Mid-Late 1990's web forms started to show up with web applications. Late 1990's JavaScript added further interaction. 2000's AJAX and Flash started to provide richer internet applications.

9. Web Usability Now Increased emphasis on making the web as rich an interface as native applications. The mobile web is the next frontier. Current Technologies are dated and are hindering growth.

10. HTML 5 and CSS3 to the Rescue HTML5 and CSS3 are the next generation of markup that will drive the web. What is the difference between HTML4 and HTML 5?

33. The Critics Say HTML5 will not get rid of Flash HTML5 doesn't use XML Syntax Too many tags / Tag Soup
