Frequently Asked Questions
What are HTML entities?
HTML entities are special codes that represent characters in HTML. They start with & and end with ;. For example, < represents <, & represents &, and " represents ".
Why do I need to encode HTML entities?
Encoding prevents browsers from interpreting special characters as HTML markup. This is crucial for security (preventing XSS attacks) and for displaying code or special characters correctly.
What is the difference between named and numeric entities?
Named entities use human-readable names like & while numeric entities use character codes like &. Both produce the same result.
Does encoding affect SEO?
No. Search engines understand HTML entities and treat them the same as the original characters.
