I have to add roll over effect to alot of buttons. And the roll effect includes adding certain swatch and change its opacity to 25%.
Ideally, effect of any simple greyish tint (with gradient) when cursor hover over would work. But since I couldn't find anything built-in, I created a new swatch of grey color with gradient and then changing it opacity to 25% works perfect for me.
Now I need script to add that swatch with certain opacity as roll over effect to buttons.
