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>
My First Heading
</h1>
<p>
My first paragraph.
</p>
<br>
none
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!
Web Browsers
The purpose of a web browser (Chrome, Edge, Firefox, Safari) is to read HTML documents and display them
correctly.
A browser does not display the HTML tags, but uses them to determine how to display the document:

<body>

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.
