An anchor tag can be described in 2 ways:
1. To create a link to another document.
2. To create a bookmark inside a document.
Anchor tags are very useful when you need to create a bookmark on the same page or another page, such as for a table of contents, terms, articles, newsletters, etc. An invisible HTML marker or target that allows a link to go to a specific page instead of the top of the page.
