There are some reserved keywords in HTML and they have special meaning to it when used in HTML documents. For example, we cannot use the greater than (<) and less than (>) signs or angle brackets within your HTML text because the browser will treat them differently and will try to draw a meaning related to the HTML tag.

So, the HTML Character entities are used to display reserved characters in HTML.

For Example:

Syntax: For using entities…

&entity_name;

OR

&#entity_number;

 

(Used for Non-Breaking space in HTML)
