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 element do not have an end tag!
