Title attribute and css selectors

Ciao,

Is it possible with css to select a visible attribute like title=""
and apply a new style to it?

For example, in <a href="http://index.html" title="Go to the
homepage">Homepage</a>
or in <img src="paris.jpg" alt="Two children running in front of the Eiffel
tower" title="Paris, 2008">, using only css, to set a different text-color or
background-color for the 'title box' that appears when i do a rollover
on the link or the image (Firefox default is a black text on a yellow
background box).



Thank you very much
