How is this Widget changing the colour of an image?
My client wants me to create something similar to the 'colored widget' shown here:
Initially I thought this seems like a fairly straight forward project, but then I noticed the button is not a button at all, but an image!
So my question is, how exactly is this possible? I notice the button works in IE7 so it cant be any HTML5 trickery?
thanks in advance!! :)
