W3C HTML Validator Invalid
Xah Lee, 2011-03-15
The W3C HTML Validator is getting annoying.
Missing Open Tag as Valid
If you have a page without a opening “body” tag, but does have a closing one, W3 HTML validation report it as valid.
Maybe it's technically valid, but quite annoying.
Test page: W3 HTML Validation Problem: No Open Body.
XHTML Style “<br />” Tag as Valid HTML4
Another problem is that, if you use the XHTML style tag such as
<br />, it's also reported as valid. W3C only gives a warning. However, this is technically invalid.
Test page: W3 HTML Validation Problem: Slash End Tag.
With this situation, at this point, you wonder what's validator supposed to be anymore.
