HTML - Entitiesquery_builder | Christopher Pisani
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.
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.
