Entities can also be used to add symbols that you don’t have on your keyboard. There are a lot of math, science, and money symbols that you can’t find on a normal keyboard. To add these symbols to an HTML page, we have to use HTML entity names.
If there is no entity name, you can use a decimal, hexadecimal, or entity number instead.
Example
<!DOCTYPE html>
<html>
<body>
<h3> Symbols Example</h3>
<p>Indian Rupee symbol <b>₹<b></p>
<p>Dollar symbol <b>#36;</b></p>
</body>
</html>
HTML Entities for Symbols
In the last chapter, we talked about HTML entities.
A normal keyboard doesn’t have a lot of symbols for math, science, and money.
You can use the entity name or the entity number (a decimal or hexadecimal reference) for the symbol to add it to an HTML page.
