Question 1

What are HTML entities?

Accepted Answer

HTML entities are text representations of special characters that would otherwise be interpreted as HTML code. For example, < becomes <, > becomes >, and & becomes &. They are used to display reserved characters safely in web pages.

Question 2

Why do I need to encode HTML entities?

Accepted Answer

If you display user-generated content or raw HTML code in a web page without encoding, it can be interpreted as HTML markup or cause XSS (cross-site scripting) security vulnerabilities. Encoding special characters prevents this.
