 HTML is a language for describing web pages.  HTML stands for Hyper Text Markup Language  HTML is a markup language  A markup language is a set of markup tags  The tags describes document content  HTML documents contain HTML tags and plain text  HTML documents are also called web pages

 HTML markup tags are usually called HTML tags  HTML tags are keywords (tag names) surrounded by angle brackets like  HTML tags normally come in pairs like and  The first tag in a pair is the start tag, the second tag is the end tag  The end tag is written like the start tag, with a forward slash before the tag name  Start and end tags are also called opening tags and closing tags

 "HTML tags" and "HTML elements" are often used to describe the same thing.  But strictly speaking, an HTML element is everything between the start tag and the end tag, including the tags:  HTML Element:  This is a paragraph.

 The purpose of a web browser (such as Google Chrome, Internet Explorer, Firefox, Safari) 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:

 Since the early days of the web, there have been many versions of HTML: VersionYear HTML1991 HTML+1993 HTML HTML HTML XHTML HTML52012 XHTML52013

 The declaration helps the browser to display a web page correctly.  There are many different documents on the web, and a browser can only display an HTML page 100% correctly if it knows the HTML type and version used.

 The comment tag is used to insert comments in the source code. Comments are not displayed in the browsers.  You can use comments to explain your code, which can help you when you edit the source code at a later date. This is especially useful if you have a lot of code.  It is also a good practice to use the comment tag to "hide" scripts from browsers without support for it (so they don't show them as plain text): 

 The declaration must be the very first thing in your HTML document, before the tag.  The declaration is not an HTML tag; it is an instruction to the web browser about what version of HTML the page is written in.  In HTML 4.01, the declaration refers to a DTD, because HTML 4.01 was based on SGML. The DTD specifies the rules for the markup language, so that the browsers render the content correctly.  HTML5 is not based on SGML, and therefore does not require a reference to a DTD. 

 HTML 5   HTML 4.01 Strict  This DTD contains all HTML elements and attributes, but does NOT INCLUDE presentational or deprecated elements (like font). Framesets are not allowed.   HTML 4.01 Transitional  This DTD contains all HTML elements and attributes, INCLUDING presentational and deprecated elements (like font). Framesets are not allowed. 

 HTML 4.01 Frameset  This DTD is equal to HTML 4.01 Transitional, but allows the use of frameset content.   XHTML 1.0 Strict  This DTD contains all HTML elements and attributes, but does NOT INCLUDE presentational or deprecated elements (like font). Framesets are not allowed. The markup must also be written as well-formed XML. 

 XHTML 1.0 Transitional  This DTD contains all HTML elements and attributes, INCLUDING presentational and deprecated elements (like font). Framesets are not allowed. The markup must also be written as well-formed XML.   XHTML 1.0 Frameset  This DTD is equal to XHTML 1.0 Transitional, but allows the use of frameset content.   XHTML 1.1  This DTD is equal to XHTML 1.0 Strict, but allows you to add modules (for example to provide ruby support for East-Asian languages). 

 Writing HTML Using Notepad or TextEdit  HTML can be edited by using a professional HTML editor like:  Adobe Dreamweaver  Microsoft Expression Web  CoffeeCup HTML Editor  However, for learning HTML we recommend a text editor like Notepad (PC) or TextEdit (Mac). We believe using a simple text editor is a good way to learn HTML.

 To start Notepad go to:  Start All Programs Accessories Notepad

 Type your HTML code into your Notepad:

 Select Save as.. in Notepad's file menu.  When you save an HTML file, you can use either the.htm or the.html file extension. There is no difference, it is entirely up to you.  Save the file in a folder that is easy to remember.

 Start your web browser and open your html file from the File, Open menu, or just browse the folder and double-click your HTML file.  The result should look much like this:
