Are there any filters that would make background image black-and-white?
I have an image set as the background image using css, but now I need to apply a filter so that an image is shown in black and white only. Ideally, I would also like to apply opacity to it.
The effect I really trying to achieve is to have background image black/white and on hover over that span element the filter would be removed, revealing the color version.
And of course it has to work in FF, Chrome, IE
