What are HTML Entities?

HTML entities are used to display reserved characters in HTML. They start with an ampersand (&) and end with a semicolon (;). This prevents the browser from interpreting these characters as HTML code.

How does it work?

Common Entities & → & < → < > → > " → " ' → '

■ 03

Sample Cases

Covers Ampersand, HTML tags, and Quotes so you can compare common inputs and outputs quickly.
