HTML tags are keywords
(tag names) surrounded by angle brackets:
HTML tags normally come in pairs like <p>
The first tag in a pair is the start tag,
the second tag is the end tag
The end tag is written like the start tag,
but with a slash
before the tag name
The start tag is often called the opening tag.
The end tag is often called the closing tag.
The purpose of a web browser (Chrome, IE, Firefox, Safari) is to read HTML documents and display them.
