To output special characters on an HTML web page, you can use the following values in your HTML code.
The format is an Ampersand (&), followed by an Entity Name or a hash (#) and the numeric code, ending with a semicolon (;).
These codes are interpreted by the browser and appear as the equivalent character to the viewer.
HTML Codes are also referred to as HTML Entities, HTML Characters or HTML Symbols.
