HTML Tags

HTML stands for Hyper Text Markup Language
HTML language, called tags, are words or acronyms surrounded by brackets. A typical HTML tag looks like this:

<tag>  Example Of An HTML Tag </tag>
There are four tags every HTML document should have. These tags define the what type of document it is, and the major sections-<HTML>, <HEAD>, <TITLE>,<BODY>. 

<HTML>

<HEAD>
<TITLE>Name Of Basic Document</TITLE>
</HEAD>

<BODY>
The content of the document
</BODY>

</HTML>

The <html> element is also known as the root element.
HTML is written in the form of HTML elements consisting of tags enclosed in angle brackets (like <html>), within the web page content. HTML tags most commonly come in pairs like <h1> and </h1>, although some tags, known as empty elements, are unpaired, for example <img>. The first tag in a pair is the start tag, the second tag is the end tag (they are also called opening tags and closing tags). In between these tags web designers can add text, tags, comments and other types of text-based content.

The purpose of a web browser is to read HTML documents and compose them into visible or audible web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page.

HTML elements form the building blocks of all websites. HTML allows images and objects to be embedded and can be used to create interactive forms. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. It can embed scripts in languages such as JavaScript which affect the behavior of HTML webpages.

Web browsers can also refer to Cascading Style Sheets (CSS) to define the appearance and layout of text and other material. The W3C, maintainer of both the HTML and the CSS standards, encourages the use of CSS over explicitly presentational HTML markup

The <html> tag is supported in all major browsers.
