HTML Classroom Learning: 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 such symbols to an HTML page, you can use the entity name or the entity number (a decimal or a hexadecimal reference) for the symbol.

Example

Display the euro sign, €, with an entity name, a decimal, and a hexadecimal value:

<p>I will display €</p>

Will display as:

I will display €
