What is an HTML Element?

An HTML element provides a structure to a Web age.

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

<tagname>Write Something Here…</tagname>

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

<h1>This is My First Heading</h1>
<p>This is My first paragraph.</p>
Start tag Element content End tag
<h1> This is My First Heading </h1>
<p> This is My first paragraph. </p>
<br> none none
Note: Some HTML elements have no content (like the <br> element). HTML elements which have no content are called empty elements. These Empty elements do not have an end tag!
