History

If you compare the HTML with the old version, you sill see that lots of contents of the contemporary HTML is incorporated in the first documentation and you will also see that more than 50 percent tags that are mentioned in the original version are still present.

As more and more people started to write the web pages and the alternatives to original software, more and more features started getting added to the HTML. There were so many features that were universally adopted like the “img” element that is used for inserting the image to the document which was first implemented in the NCSA Mosaic. There were some that were proprietary and only used on 1 or 2 browsers. There were an increasing demand for standardization, that the web browsing software authors had the document called as the specifications that were clearly defined what the HTML looked like and therefore they were in a position to judge whether they were actually missing out the implementation of the HTML parts or not.

The InternetEngineeringTaskForce (IETF) is a standard body concerned with the inter operations of the internet. The IETF published the draft proposal of the HTML in the year 1993. In 1994, the same thing expired without becoming the standard. Later this promoted the IETF for creating the working group for looking forward at the HTML standardization.

The HTML 2.0 version was written in 1995, picking up the idea from the original draft of the HTML. The alternate form of the proposal was called as the HTML+, which was widely used as a source for the new elements that were implemented by the browsers like the method of inserting images in a document, etc.

In the 1995 end, followed the draft of the HTML 3.0, but the working of this was stopped due to lack of support from the browser makers. Then the HTML 3.2 dumped many new features of the 3.0 version. Instead it adopted many creations of the previously popular Mosaic and the Netscape navigator browsers.

In 1997 the HTML 4.0 adopted many browser specific extensions for rationalizing and cleaning up of the HTML. Various elements wee marked as depreciated or obsolete and removed in the later version. In 1999, the 4.01 version was published, which is then latest version, although the HTML 5 version is currently in the drafting process.
In the year 2000, the XHTML version 1.0 which is HTML restructured for making a legal XML document.

Structure of HTML document
The document initially starts with the document type which could be elements or doctype. This describes the type of HTML being used. This will help the browsers to determine the way of interpreting the document and also work out whether it’s following the said rules.

Then you can actually see the HTML element “Opening Tag”. This is wrapper around the whole document. The final thing in the HTML document is the closing tag of HTML.

There is a head element in the elements of the HTML. This is a form of wrapper which contains information regarding the document which is commonly called as the megadata. In the head is title element that defines the test heading in menu bar.
After this the body element follows, which is a wrapper containing the actual contents of a page. In such a case, the level 1 header (h1) element is there containing the text “hi everyone”. Many a times, the elements have other elements. The document body will end up involving lots of the nested elements. The division of the page creates overall document structure, and will also contain subdivisions containing headings, lists, paragraphs, etc. The paragraphs might contain elements that will make the links of the other documents.
