HTML Concept, History, How It Works & Tags


What is Html?

HTML holds for HyperText Markup Language English, meaning Markup Language HyperText. This is the name of the programming language used in the elaboration of Web pages, and which serves as a reference standard for coding and structuring them, through a code of the same name (Html).

The W3C, or World Wide Web Consortium, an organization dedicated to the standardization of the parameters of the Network, uses Html as the most important language web, and to which virtually all browsers and explorers have adapted. It is crucial, then, for the development and expansion of the Network.

This code operates based on the differentiation and location of the different elements that make up the Web page. Thus, the code is light and merely textual. Still, it contains the URL addresses of the images, audios, videos and other content that will be retrieved by the browser to assemble the page, as well as the indications for the graphic and aesthetic representation of the text that is used. Find in it.

HTML has gone through various versions and modifications, moving towards a more efficient and faster-operating model, which forces different browser software companies to apply consecutive patches to their products to update them with each new version.

Html history

The first version of this code appeared in 1991 and was written by Tim Berners-Lee (TBL), is little more than an initial design of 18 elements, 13 of which are still preserved. It was considered little more than a variant of the General Standard Markup Language (SGML) in use and consisting of a tag language. Still, as early as 1993, its virtues and its power in the standardization of Internet languages ​​were recognized.

Then work began on Html +, a more developed version, and in 1995 the third version of the standard was obtained: HTML 3.0, whose successive updates (3.1 and 3.2) were very successful in the first popular Netscape and Mosaic browsers. HTML 4.0 would appear in 1997, already as a recommendation of the W3C, and finally in 2006 the most recent version, HTML 5.0.

How does Html work?

The Html language operates on the basis of written bookmarks (which appear between angle quotes: <html>), from which the appearance and internal order of a web page are encrypted, as well as the scripts or routines that operate within them. Said source code acts as DNA of the Web page, telling the browser where to obtain the resources for its representation and in what order, sequence and way to establish them. And following the code to the letter, the browser gives us the experience of Web browsing.

For this, Html operates based on a set of components, such as:

  • Elements. The basic bricks of the Html language are used to represent the content and its attributes, as well as marking the parameters of the language itself, such as the starting point of the command chain and the closing point, or special needs.
  • Attributes. Specifications regarding the value, colour, position, etc. of the factors included in the code. They usually consist of a series of logical or numerical instructions.

What is an Html tag?

The instructions with which the code is composed are called Html tags, that is, the entries surrounded by angle quotes and that have a specific value in the set, which will then be read by the browser and translated on a Web page. These tags should open <> and then close </> when they are no longer needed, in the correct order and the correct sequence so that no errors arise.

Some examples of labels are:

  • <html>. A command that starts the instruction string, which is the Html code and closes with </html> at the end of the programming document.
  • <head>. Which defines the header of the Html document, which is linked to the title of the browser window and contains sub-elements such as <title> (title), <link> (to link to style sheets or aesthetic models), <meta> (to refer information about the authorship of the code), etc.
  • <img>. That refers to images and is usually accompanied by the route where it is located.
  • <a>. To enter both internal and external hyperlinks, using the href attribute and the URL address where the hyperlink will lead.
  • <div>. To enter divisions within the web page.


HTML5 is the latest version of this programming language, published in October 2014 by the W3C consortium. This modernization of the language replaced obsolete tags with current versions and takes advantage of new technologies and web needs such as forms, viewers, large data sets, etc.
