HTML symbols are characters generally not found on a keyboard.
They include mathematical operators, greek letters, currencies, and more.
HTML entity notation &...;
)
If no entity name is available for a symbol, then use the entity number or hex notation.
Three symbol pairs created with entity name notation and entity number notation.
The symbols display the same.
Below is a listing of all HTML symbols.
