Frequently Asked Questions

What are HTML entities used for?

HTML entities represent special characters in HTML. For example, < displays as '<'. They're essential for safely embedding user-generated content in web pages and preventing XSS attacks.

Does this prevent all XSS?

Encoding &, <, >, and " as HTML entities is a key part of XSS prevention but not the complete solution. Always use proper security headers and Content Security Policy alongside encoding.
