In HTML, some characters can’t be typed directly into the code because the browser might interpret them as HTML commands or they might not be available on your keyboard.
HTML entities are special codes that represent these characters.

1. Why HTML Entities are Needed

• To display reserved characters like < or > (used in tags).
• To display special symbols like ©, ®, €, etc.
• To show characters from other languages without encoding issues.

Example:

<p>2 &lt; 5 and 5 &gt; 2</p>

Output:
2 < 5 and 5 > 2

2. Structure of an HTML Entity

There are two types:

1. Named entities: Start with &, end with ; → © → ©
2. Numeric entities:
   • Decimal: © → ©
   • Hexadecimal: © → ©
