Frequently Asked Questions
What are HTML entities?
HTML entities are special codes used to display reserved characters (<, >, &, etc.) and special symbols in HTML. They start with & and end with ; like < for <.
When should I encode HTML entities?
Encode when displaying user input to prevent XSS attacks, when you need special characters in HTML content, or when characters might break your HTML structure.
What's the difference between named and numeric entities?
Named entities use readable names (&, <) while numeric entities use character codes (&, <). Numeric entities support more characters.
Should I encode all characters?
No, only encode characters that have special meaning in HTML (<, >, &, ", ') or aren't in the standard ASCII range. Over-encoding makes content harder to read.
Are HTML entities case-sensitive?
Yes, named entities are case-sensitive. & is valid but & is not. Numeric entities work regardless of case.
