What is HTML, Hypertext Markup Language

The Hypertext Markup Language (HTML, hypertext dt)-markup language, often referred to simply as hypertext, is a text-based markup language for structuring of content such as text, images and hyperlinks in documents. HTML documents are the foundation of the World Wide Web and are represented by a Web browser. In addition to the content displayed by the browser, an HTML Web page provides additional information in the form of metadata that provide.

For example, the language used in the text or the author information to summarize the content of the text. The markup language is developed by the World Wide Web Consortium (W3C). Current is the HTML version 4.01. (HTML5 is being developed). Extensible Hypertext Markup Language (XHTML) was intended as a temporary replacement for HTML 4.01.

Syntax

Most HTML elements will be marked by a tag pair, that is a start tag and a corresponding closing or end tag. A start tag always begins with the characters “<” (less than). The following is the actual name of the tag (e.g. “p” for a paragraph or “h1″ for a headline), and optionally a list of its attributes (additional information about the item), with a “>” (greater than) the start tag is closed.

A final part consists of the characters ““. A closing date may have no attributes. The matched start and end tags, together with the intervening text (content) is an element of general SGML specification. These elements can be subject to rules which are specified in a document type definition (DTD) to nest:

A paragraph of text that contains a emphatic word.

In older versions of HTML were allowed to omit certain tags if they had no attributes (eg … , … , body, … ).

For certain types the final part is missing (for example) or . In addition, playing in tags case-sensitive does not matter (eg

1. • One line of text,is continued here.

HTML tags are not available for the presentation that tells the web browser how the text with formatting (between tags) is visually. Instead, a structuring tag is awarded, with the text fields being assigned a meaning, for example

for a headline, … for a paragraph of text and … for underlined text.

As this meaning is conveyed to the user end (in the case of a headline, for example) by larger, bold font, it is initially left to the browser, and depends on the output environment. For although HTML documents are usually displayed on computer screens, it can be spent on other media such as on paper or by voice.

To take on the presentation of an HTML document in a variety of media influence are CSS style sheets. Therefore apply the elements and attributes for presentation as … , … and width as obsolete and should be avoided generally. Most of the elements and attributes for the presentation were in the HTML 4.01 specification as a (deprecated Sheet marked).

Reading the source code and processing the available information is Parsi, the processing for the output device to render: HTML describes how the browser or editor has to understand the distinctions of the text “,” not translated into the presentation.

Thus

1. • while stating a heading, but does not represent any font or font style, they are – here are just some normal defaults naturalized, but are not part of the HTML specification.

This property means that the HTML does not lend itself to present a document exactly as the author wants it, but the document is largely adapted to the technical realities and needs of the reader.
