HTML Tag Reference
Special Symbols and Entities
To use the upper ASCII characters in HTML documents, you need to type decimal references or entity references.
Decimal references have the format &#nnn
; where nnn
is a number that references the character. Entity references have the format &nnn;
where nnn
is a text string that references the character.
In addition to entity and decimal references, HTML has reserved
characters that have special meanings in HTML files. For example, HTML
uses angle brackets to enclose HTML tags. If you want to use an angle
bracket in your text, you have to use a special character or entity
reference; otherwise, Netscape Navigator (or other web browser) might
misinterpret the character and display incorrect text or even an error
message.
