No. attribute can be used with pretty much any HTML element - it does not necessarily have to be. I replaced  from your code with bracket link and   class because   would not really work on Wikia that way. The link seems to work fine, though. Based on your code, you seem to be aiming to show button with  cursor and have no link if   parameter is unfilled, and upon it being filled, to show the button with rollover effect which links to whatever   is filled with - and the code I posted works fine just as that: you can see a working sample there. If a bracket link has its destination containing an unfilled parameter, it would result what your screenshot shows - while the code I posted is supposed to have a button which does not seek any link upon  being unfilled as I said above. So did you use my posted code exactly as it is or did you change something from it? If you did, it would be great if you could post what you are using so that I could have an exact idea of the issue. :)
