Multiple values for rel attribute

Question

Can I have multiple values for rel attributes? Like so:

<a href="#" rel="value1 nofollow">Link</a> 

.. is it valid and cross-browser compatible?

Answer 1

It's valid. I'm not sure if it's supported by all browsers, though, but I would guess that it is.

rel = link-types [CI] This attribute describes the relationship from the current document to the anchor specified by the href attribute. The value of this attribute is a space-separated list of link types.

Answer 2

Yes it's valid and it works on all browsers, including IE7 and IE8
