Frequently Asked Questions
What is an HTML entity?
An HTML entity is a string of characters that represents a reserved character (like < or >) or an invisible character (like a non-breaking space) in HTML. They start with an ampersand (&) and end with a semicolon (;).
Why do I need to encode HTML entities?
Encoding HTML entities prevents browsers from interpreting text (like `<script>`) as executable code. This is crucial for rendering code snippets safely and preventing Cross-Site Scripting (XSS) issues.
What is the difference between named and numeric entities?
Named entities use word abbreviations (like `<` for less-than), while numeric entities use character codes (like `<` or hexadecimal `<`).
