What are HTML Entities?
HTML Entities are strings of characters that browsers use to display reserved characters or symbols that cannot be easily typed on a keyboard. They start with an ampersand (`&`) and end with a semicolon (`;`).
For example, the less-than sign (`<`) is a reserved character in HTML because it is used to start a tag. To display it literally on a webpage, you must use the HTML entity `<`.
Security (XSS Protection)
Encoding user input is a fundamental security practice. By converting characters like `<` and `>` into entities, you prevent browsers from executing them as code, mitigating Cross-Site Scripting (XSS) attacks.
Special Symbols
Entities allow you to display symbols like © (`©`), ™ (`™`), and € (`€`) consistently across all browsers and character sets.
Code Documentation
When writing technical blogs or documentation, you need to encode HTML snippets so they are displayed as text rather than being rendered by the browser as actual elements.
Non-ASCII Characters
While UTF-8 handles most characters, using HTML entities ensures that accented characters and foreign scripts are rendered correctly even if the file's encoding is misinterpreted.
