What's HTML Entity
An HTML entity is a piece of text ("string") that begins with an ampersand (&) and ends with a semicolon (;). Entities are frequently used to display reserved characters (which would otherwise be interpreted as HTML code), and invisible characters (like non-breaking spaces). You can also use them in place of other characters that are difficult to type with a standard keyboard.
Reserved HTML Entities
Some special characters are reserved for use in HTML, meaning that your browser will parse them as HTML code. For example, if you use the less-than (<) sign, the browser interprets any text that follows as a tag. To display these characters as text, replace them with their corresponding character entities, as shown in the following table.
| Character | HTML Entity | Description |
