HTML development history

Time:2019-12-15

Html is the abbreviation of hypertext markup language. Unlike C or Java programming languages, html is composed of tags. Through the tag, you can insert text, picture, link, audio, video and other elements into the web page to describe the web page. Like windows, with the development of technology, HTML has experienced many version updates.

HTML 1.0: in June 1993, HTML was released as a working draft of the Internet Engineering Task Force (IETF) (note, it’s a draft, not a standard)

Html2.0: published as RFC 1866 in November 1995, after RFC 2854 was published in June 2000, it was declared obsolete;

HTML 3.2: Published by W3C on January 14, 1997, as the recommended standard;

Html4.0: December 18, 1997, W3C recommended standard;

Html4.01: December 24, 1999, a minor improvement based on html4.0, recommended by W3C;

After the release of html4.01, it has been able to meet the daily needs of Internet Names for a long time. However, with the passage of time, people began to listen to songs, play games and watch videos on the Internet. However, video, audio and animation cannot be directly inserted into the web pages supported by HTML. At this time, Adobe took the lead in seizing the business opportunities. Flash, as a browser plug-in, met the above needs.

What is W3C doing at this time?

They’re focused on XHTML 2.0, which we’ll talk about later.

Seeing that W3C wants to give up HTML, in 2004, opera, Mozilla foundation and apple, these browser manufacturers jointly established whatwg (Internet Hypertext Application Technology Working Group) to continue to promote the standardization of HTML (at this time, the main goal is to develop new functions to replace plug-ins). In 2006, W3C expressed interest in participating in the development. In 2007, W3C accepted the web Apple proposed by whtawg Indications1.0, and officially named the new HTML “HTML5”. On January 22, 2008, the first formal draft of HTML5 was published; on October 29, 2014, W3C announced that after nearly eight years of hard work, the standard specification was finally formulated.

It needs to be inserted here. W3C isWorld Wide Web AllianceFounded in 1994, it is the most authoritative and influential international neutral technical standard institution in the field of web technology, which specializes in developing standards and implementation guidelines for web technology. As for why there is no 3.0, 3.1, there are too many areas to improve when formulating standards, which causes a lot of controversy, and there is no suitable browser support to be replaced by subsequent versions.

so,HTML5 is the standard, is the fifth revision of the HTML standard, andNot technology

We usually say H5 is HTML5, which is not only a standard, but also a combination of HTML, CSS3, JavaScript and web API.

Just now we talked about XHTML. What the hell is this???

XHTML(eXtensible HyperText Markup Language):Extensible HyperText Markup Language。 It is also a kind of markup language, similar to HTML, but more strict in syntax and better in compatibility.

XHTML 1.0 was released on January 26, 2000, which is the recommendation standard of W3C. It was reissued on August 1, 2002, compatible with html4.01. At that time, XHTML as a web development standard was a very good choice. As you can see from the following story, great changes have taken place since the release of HTML5: the development of XHTML stopped at the end of 2009 due to the impact of HTML5.
