[QUOTE=puoidirloatutti] hi, i read a lot of post but i can't find how to change the buttons style. color, style, font etc etc.
thank you all[/QUOTE]
Hi! I'm sure you've figured it our by now, but you should take a look here
as this thread describes how to make sprites clickable (like buttons) using the mouse object. That way you can make your buttons as crazy as you want in Photoshop, Gimp, whatever, and import them into your game, rather than have to use CSS.
Hope this helps someone!
