Example Explained

The < !DOCTYPE html > declaration defines that this document is an HTML5 document
The < html > element is the root element of an HTML page
The < head > element contains meta information about the HTML page
The < title > 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 > 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 > element defines a large heading
The < p > element defines a paragraph

What is an HTML Element?

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>

Start tag	Element content	End tag
<h1>	<p>	<br>
My First Heading	My first paragraph.	none
</h1>	</p>	none

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!

HTML Page Structure

Note: The content inside the <body> section will be displayed in a browser. The content inside the <title> element will be shown in the browser's title bar or in the page's tab.
