HTML Symbols
HTML Symbol Entities
HTML entities were described in the previous chapter.
Many mathematical, technical, and currency symbols, are not present on a normal keyboard.
To add these symbols to an HTML page, you can use an HTML entity name.
If no entity name exists, you can use an entity number; a decimal (or hexadecimal) reference.
 |
If you use an HTML entity name or a hexadecimal number, the character will always display
correctly. This is independent of what character set (encoding) your page uses! |
|---|
Example
<p>I will display €</p>
<p>I will display €</p>
<p>I will display €</p>
Will display as:
I will display €
I will display €
I will display €
