I use W3C validator to check my CSS and my XHTML site. But, It showed me some errors that is actually not error. For example:

<meta name="keywords" content="Test">

The red color is an error showed by W3 validator. I'm confused with this, to my know, that's an exact code. I get it from wordpress theme. And more errors same like that. What should I do to fix this problem?

Thanks for answering

because ">" is NOT the correct closing character for "self-closing" elements in XHTML.

You should use " />"

I see, thanks bro, I'll try it again
