html - Do I need a "/" at the end of an or tag, etc.?

Do you need to have a / at the end of an img tag? I saw an example on W3schools.com without a /:

I know it isn't necessary to self-close the tag, at least in my browser, but should I do so?

Answer

The / is only required for XHTML & XML.

If you're using a HTML5 doctype, then there's no need to terminate self-closing tags in this way.

This applies to ,
,

---

etc.

I.e. Just use ,
and

---

.

If you need an empty element (like a div), don't use

, instead use

. This is important since in HTML5, the slash is ignored and

is interpreted as

without a closing tag.
