HTML Entities & Symbols

In HTML, certain characters like <, >, &, or " have special meanings and cannot be written directly inside the document - doing so can confuse the browser.
To display these characters properly, we use HTML entities.

An HTML entity is a code that begins with an ampersand (&) and ends with a semicolon (;).
They are used to represent characters that are either reserved in HTML or not available on a standard keyboard.

Syntax

html

&entity_name;
OR
&#entity_number;

Example

html

<p>10 < 20 && 20 > 10</p>

Output:

10 < 20 && 20 > 10

Why Use HTML Entities?

  • To display reserved characters like < or > without breaking code.
  • To insert special characters (€, ©, ™, etc.) not on the keyboard.
  • To ensure compatibility across different browsers and devices.
  • To enhance readability and SEO safety (especially for symbols and quotes).
