HTML is the standard markup language for creating Web pages.

What is HTML?

HTML stands for HyperText Markup Language
HTML is the standard markup language for creating Web pages
HTML describes the structure of a Web page
HTML consists of a series of elements
HTML elements tell the browser how to display the content
HTML elements label pieces of content such as "this is a heading", "this is a paragraph", "this is a link", etc.

<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>

<h1>My First Heading</h1>
<p>My first paragraph.</p>

</body>
</html>

The <!DOCTYPE html> the declaration defines that this document is an HTML5 document
The <html> element is the root element of an HTML page
The <head> the element contains meta-information about the HTML page
The <title> the element specifies a title for the HTML page (which is shown in the browser's title bar or in the page's tab)
The <body> the element defines the document's body and is a container for all the visible contents, such as headings, paragraphs, images, hyperlinks, tables, lists, etc.
The <h1> the element defines a large heading
The <p> the element defines a paragraph

An HTML element is defined by a start tag, some content, and an end tag:

<tagname>Content goes here...</tagname>

The HTML element is everything from the start tag to the end tag:

<h1>My First Heading</h1>

<p>My first paragraph.</p>

Note: Some HTML elements have no content (like the <br> element). These elements are called empty elements. Empty elements do not have an end tag!
