Frequently Asked Questions

What are HTML entities?

HTML entities are special codes that represent characters reserved in HTML (like <, >, &) or characters not easily typed on a keyboard. For example, &amp;lt; represents < and &amp;amp; represents &.

When should I encode HTML entities?

Always encode user-provided content before inserting it into HTML to prevent XSS (Cross-Site Scripting) attacks. This converts < to &lt; and & to &amp;, making it safe to display.
