HTML elements can contain formatting instructions, semantic meaning, and content.
HTML elements are used to denote document parts such as headers, paragraphs, and footers and to embed content such such as hyperlinks, text, and images.
The HTML element is everything from the start tag to the end tag:
<tagname>Content goes here...</tagname>
Examples:
<h1>My First Heading</h1>
<p>My first paragraph.</p>
