HTML - Hyper Text Markup Language

Basics:

What is HTML?

HTML is a language for describing web pages.

• HTML stands for Hyper Text Markup Language
• HTML is not a programming language, it is a markup language
• A markup language is a set of markup tags
• HTML uses markup tags to describe web pages

HTML Tags

HTML markup tags are usually called HTML tags

• HTML tags are keywords surrounded by angle brackets “< >”
• The first tag in a pair is the start tag, the second tag is the end tag
• The closing tag should be ended with a “/”

· Start and end tags are also called opening tags and closing tags

HTML Documents = Web Pages

• HTML documents describe web pages
• HTML documents contain HTML tags and plain text
• HTML documents are also called web pages

The purpose of a web browser (like Internet Explorer or Firefox) is to read HTML documents and display them as web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page:

1. Eg: starting program for HTML basic

	1. html 2. body 3. h1 My First Heading /h1 4. p My first paragraph. /p 5. /body 6. /html

Example Explained

• The first line describes the web page
• The second line is the visible page content
• The third line is displayed as a heading
• The fourth line is displayed as a paragraph

.HTM or .HTML File Extension?

When you save an HTML file, you can use either the .htm or the .html file extension. We use .htm in our examples. It is a habit from the past, when the software only allowed three letters in file extensions.With new software it is perfectly safe to use .html.
