Tags

In HTML, tags are commonly defined as a set of characters constituting a formatted command for a web page. They are used for making elements for the web page’s markup. During the early days of the World Wide Web, tags were responsible for a majority of the web’s code.

<element-name> content </element-name>

<self-closing-element-tag />

A single tag is made of an opening angle bracket <, followed by the element-name, followed by the closing angle bracket. While most elements are made of opening and closing tags but some are self-closing. Furthermore, some self-closing elements like <br> can have a slash at the end like so: <br />.
