HTML Entities

HTML entities are special codes used in HTML to represent characters that have reserved meanings or are not easily typed on a keyboard, such as <, >, &, and non-ASCII characters like © or €. They consist of an ampersand (&), a name or number, and a semicolon (;), ensuring proper display and avoiding conflicts with HTML syntax. This mechanism is essential for writing valid and accessible web content.

Also known as: HTML character entities, HTML escape codes, HTML special characters, Character references, Entity codes

Why learn HTML Entities?

Developers should learn HTML entities to handle special characters in web development, such as displaying mathematical symbols (e.g., ∑), currency signs (e.g., $), or reserved characters like quotes and angle brackets without breaking HTML code. They are crucial for internationalization, accessibility (e.g., using non-breaking spaces), and preventing cross-site scripting (XSS) attacks by escaping user input.
