Frequently Asked Questions
What is HTML encoding?
HTML encoding converts characters that have special meaning in HTML (like <, >, &, \") into their corresponding HTML entities (like <, >, &, "). This ensures the browser displays them as text rather than interpreting them as code.
Why do I need to encode HTML?
Encoding is critical for security (preventing Cross-Site Scripting or XSS attacks) and display correctness. If you want to show code snippets on a webpage, you must encode the brackets; otherwise, the browser will try to render the tags instead of showing them.
What is an HTML entity?
An HTML entity is a string of characters beginning with an ampersand (&) and ending with a semicolon (;). It represents a specific character. For example, the copyright symbol © is represented as ©.
