Explanation:

Hypertext Markup language (HTML) is the standard language for describing web pages. It is a tagging language for achieving fonts, colour, graphic and hyperlink effects on webpages.

HTML tags are hidden keywords within webpages that determines how the web browsers format and display the content. Most times, tags have the opening and the closing parts which are usually the same except for the addition of a forward slash ( / ) in the closing tag.

HTML comments are not displayed in the browser, but they can help document your HTML source code. The comment tag is written as:

< ! - -    This is my comment      - - >

Note that there is an exclamation point (!) in the beginning tag, but not in the closing tag.
