HTML and CSS Reference
Not all characters available on the web are available on our keyboards. So what happens
when we want to add special characters like a copyright symbol (©) or a degree (°)? HTML
supports all these characters along with about 250 relatives, including mathematical sym-
bols and special letters. To add them to our web page, we need to use what is known as an
HTML character entity. An HTML character entity is initiated by the ampersand (&) sym-
bol, followed by a keyword (or ASCII code) and concluded with the semicolon (;) symbol.
For example, the HTML character code for a non-breaking space will be written as .
Other HTML character entities are presented in the following table:
