HTML stands for Hypertext Markup Language. It a web development coding system whose codes are recognized by web browsers.

For example, Tags can be used to change the font size and tags can be used to embed (fix or set securely) images into a web page. HTML is not case sensitive. These files are then saved with the file extension .htm or .html.

Hypertext is text displayed on a computer or other electronic device with references (hyperlinks) to other text that the reader can immediately access, usually by a mouse click or keypress sequence. Apart from running text, hypertext may contain tables, images and other presentational devices. Hypertext is the underlying concept defining the structure of the World Wide Web, making it an easy-to-use and flexible format to share information over the Internet.

A hyperlink (or link) is a reference to a document that the reader can directly follow, or that is followed automatically. A hyperlink points to a whole document or to a specific element within a document.

Hypermedia, a term derived from hypertext, it extends the notion of the hypertext link to include links among any set of multimedia objects, including sound, motion video, and virtual reality.

HTML Tags And Their Meaning
Tags are instructions that are embedded directly into the text of a HTML document. Each HTML tag describes that the browser should do something instead of simply displaying the text. In HTML, the tags begin with (<) and end with (>)

HTML tags can be of three types. These are:


 * 1) Paired Tags
 * 2) Unpaired Tags
 * 3) Comments

Paired Tags:

A tag is said to be a paired tag if the text is placed between a tag and its companion tag. In paired tags, the first tag is referred to as Opening Tag and the second tag is referred to as Closing Tag. Tags that require an Opening and Closing tag such as < H1 >< /H1 > where the closing tag contains is preceded with a forward slash (/).

Example:

< i >'This text is in italics. < /i > Note: Here < i > is called opening tag. and < /i > is called closing tag.

Unpaired Tags:

An unpaired tag does not have a companion tag. Unpaired tags are also known as Singular or Stand-Alone Tags. Tags that only require one element e.g < HR > horizontal rule.

Example :

, ' etc. These tags does not require any companion tag.

Comments:

Text within the HTML source code are not displayed by the browser and must use the following format:

Document Setup: ... Encloses the entire HTML document ... - Designates the file is an HTML document. ... - HTML Header. ... - Document Title (placed within the header). ... - HTML Body (main document contents)
