About HTML Entities

HTML entities are used to display reserved characters in HTML and to display characters that are not present on the keyboard. They begin with an ampersand (&) and end with a semicolon (;).

Why Use HTML Entities?

  • Reserved Characters: Display <, >, & in HTML
  • XSS Prevention: Escape user input safely
  • Special Symbols: Display ©, ®, ™, etc.
  • Non-ASCII: Ensure compatibility across encodings

Entity Types

  • Named: &lt; (easier to read)
  • Numeric: &#60; (decimal code point)
  • Hex: &#x3C; (hexadecimal code point)
  • All Valid: Browser interprets all formats
Security Note: Always encode user-generated content before displaying in HTML to prevent XSS (Cross-Site Scripting) attacks. At minimum, encode < > & " and '.
