What is an HTML Entity?
An HTML entity is a piece of text that starts with an ampersand (&) and ends with a semicolon (;). Entities are commonly used to display reserved characters, like < or >, which would otherwise be interpreted as HTML code. They can also represent invisible characters (e.g., non-breaking spaces) or special characters that are difficult to type on a standard keyboard.
For example:
<represents the less-than symbol ("<").&represents the ampersand ("&").
