Frequently Asked Questions

HTML entities are special codes used to represent characters that have meaning in HTML syntax. For example, < is represented as < and & is represented as &. Using entities ensures these characters display correctly instead of being interpreted as HTML code.

HTML encoding prevents cross-site scripting (XSS) attacks by converting potentially dangerous characters into harmless entity codes. Without encoding, user input containing <script> tags could execute malicious JavaScript in other users' browsers.

The most critical characters to encode are: < (less than), > (greater than), & (ampersand), " (double quote), and ' (single quote/apostrophe). These characters have special meaning in HTML and can cause display issues or security vulnerabilities if not encoded.
