I just ran w3 validator on my site and it came back with this error
Error Line 103 column 49: there is no attribute "target". <a href="http://www.anikafoundation.com" target="_blank">the anika foundation</a>
So I did some reading and found out that xhtml 1.0 strict doesn't support target attributes. I found a way around this here but am curious to know whether this is the best way to achieve the original purpose of the "_blank" attribute.
