❓ Frequently Asked Questions
What are HTML entities?
HTML entities are special codes used to display reserved characters in HTML that would otherwise be interpreted as HTML code. They start with & and end with ;. For example, < displays as < instead of being interpreted as the start of an HTML tag.
What's the difference between named and numeric entities?
Named entities use descriptive names (like © for ©), while numeric entities use the character's Unicode number (like © for ©). Both display the same character, but named entities are more readable while numeric entities support more characters.
When should I use HTML entities?
Use HTML entities when: • Displaying reserved HTML characters like <, >, &, " in web content • Including special symbols that might not be on your keyboard • Ensuring proper display across different character encodings • Preventing XSS attacks by encoding user input • Creating HTML emails that display correctly
Which characters must always be encoded?
The five characters that must always be encoded in HTML content are: • & (ampersand) → & • < (less than) → < • > (greater than) → > • " (double quote) → " (in attributes) • ' (single quote) → ' (in XHTML)
