Most Web pages are written in HTML (Hypertext Markup Language). HTML was invented by European Laboratory for Particle Physics (CERN, Switzerland) to allow researchers to structured documents via a network of computers. Of structured documents, we mean to hold a text document with different headings, paragraphs and lists, or to create tables to manage data in tabular form (little as in Excel), and link it to other documents in a non-linear (hyperlink). HTML is platform independent: Since the HTML pages of text only files (take a look at the source code for your favorite browser to see what I mean) can be any computer to read it, regardless of which system the user uses (such as Unix, Windows or Mac). But in the 1990s and the very rapid development of World Wide Web, a problem began to emerge. HTML was originally designed to handle relatively simple documents. But with the arrival of graphical browsers, and a large public access to the Web, designers became more and more demanding, and although there is a language that was created mainly to organize the content and structure, it was used more and more to control the presentation: a very well-known example is the use of tables to control presentation. Tables were developed to handle tabular data, full stop. But as sites began to appear everywhere, designers began to require more complex pages, such as a layout organized in several columns, which HTML could not and would never do. So they found a way to get around this limitation, why not use tables to achieve such representation? Also, at the same time, reached a browser war between Netscape Navigator and Internet Explorer’s crown: This led to the development of these two companies with many of his own additions (ie, Marquee or Netscape parts wink), so that they did not work in the competitor’s browser . While HTML was meant to be a universal way of organizing and sharing documents in a simple way, it became increasingly fragmented and also design web pages using tables did not work as consistently as designers expected: some layout and could be broken if you use ” wrong “browser. This was the era of the logos proudly assert that they are best viewed with Netscape “or” best viewed with Internet Explorer? “. Finally, the size of the markup, compared to the actual content, it was messy and unnecessarily heavy. And then came CSS. .. This division of the World Wide Web and their own limitations of HTML language, first led to the standardization of the most useful own extensions and rejection of the second (blinking text, and so on). This was the World Wide Web Consortium’s (the principal international standardization organizations for the World Wide Web) important task with html 3rd 2nd The second idea was to stop the misuse of HTML to present . By using a separate stylesheet to control the presentation, the HTML would retain its original use, to organize the records. CSS Level 1 was developed and finally adopted in 1996 by W3C, despite an almost complete implementation of the specification was not achieved for all browsers by the end of the century . Finally, there was a way to separate structure from the presentation itself, which meant that the code has been reduced in size and complexity. In addition, designers to create stylesheets depending on usage (better accessibiliity with large text option for users with visual impairment, for example, or layout optimized for printers, PDAs, etc.). CSS level 2 was launched in 1998 with new features, and although it is still a work in progress, current versions of CSS in combination with the rapid development of XML languages, making it possible to create websites in a much more efficient manner.
