The thing to do if you might be setting the value of "display" on  
either block or inline elements is to set it to the empty string "".  
That way, it will just revert to its default value, or any value  
specified in a stylesheet that overrides the default. But generally,  
the class-setting technique described earlier in this thread by Mark  
Kelly is the best way to go, if possible.
