HTML documents are composed of elements, which are written with a start tag (or opening tag), an end tag (or closing tag), and content in between:
An HTML element is everything, from the start tag to the end tag. Below are examples of a few HTML elements:
| Start tag | Element content | End tag |
| <title> | My First Title | </title> |
| <h1> | My First Heading | </h1> |
| <p> | My first paragraph. | </p> |
| <br> |
Some HTML elements do not have an end tag, nor any content.
