What is it?
HTML entities are sequences of characters that begin with an ampersand (&) and end with a semicolon (;). They are used to represent special characters in HTML that would otherwise be interpreted as code. For example, the less-than sign (<) must be written as < in HTML to prevent it from being treated as the start of an HTML tag. There are three types of HTML entities: named entities (like © for ©), decimal entities (like © for ©), and hexadecimal entities (like © for ©).
