HTML is the programming language that has been instrumental in bringing about this revolution called ‘Internet’. ‘HTML’ fascinates a lot of people. There are people who want to learn HTML in order to try their hands at developing a website on their own. For the website designers and developers, HTML is their bread and butter. They use HTML to bring websites to life. This community of programmers and developers is also in constant search of new HTML techniques that will enhance their skills further.

Early versions of HTML were defined with looser syntactic rules which helped its adoption by those unfamiliar with web publishing. Web browsers commonly made assumptions about intent and proceeded with rendering of the page. Over time, the trend in the official standards has been to create an increasingly strict language syntax; however, browsers still continue to render pages that are far from valid HTML.XHTML, which applies the stricter rules of XML to HTML to make it easier to process and maintain, is the W3C's successor to HTML. As such, many consider XHTML to be the "current version" of HTML, but it is a separate, parallel standard; the W3C continues to recommend the use of either XHTML 1.1, XHTML 1.0, or HTML 4.01 for web publishing.
