Frequently Asked Questions
QWhat are HTML entities?
HTML entities are special text sequences that represent reserved HTML characters. For example, < represents < and & represents &. They prevent browsers from interpreting the characters as HTML markup.
QWhy should I encode HTML output?
Unescaped user input embedded in HTML can allow Cross-Site Scripting (XSS) attacks where malicious scripts are injected into your page. Always encode untrusted content before rendering it as HTML.
