List of HTML Self-Closing Tags
Here's a complete list of self-closing tags for HTML5. These are called “void-elements” in HTML spec.
<area /> <base /> <br /> <col /> <command /> <embed /> <hr /> <img /> <input /> <keygen /> <link /> <menuitem /> <meta /> <param /> <source /> <track /> <wbr />
The space before the slash is optional.
Is the Ending Slash Optional?
- HTML5: the slash is optional.
- HTML4: the slash is technically invalid. However, it's accepted by W3C's HTML validator.
- XHTML: The slash is REQUIRED.
I recommend to always add the slash. Because, it provides a visual clue of non-closing tags.
XHTML Supports Self-Closing Syntax for All Tags
In XML/XHTML, any tag can be self-closed by the ending slash
When you test XML, you have to make sure the server is sending the correct Internet media type as XHTML (For example,
application/xhtml+xml), otherwise browsers will treat it as HTML, regardless of the DOCTYPE in your file.
