Hey there, got a slight issue. I have a character on the top layer, then below it is the orange box that needs to be a rollover button, unfortunately the character's transparency is over it and I you can't rollover it. Is there a way to ignore the transparency of an image?
No unless you decide to use an interactive SVG. See tut here http://www.youtube.com/watch?v=4UEB6gaLKuw .
if your character does not move then use an SVG file with paths. see Edge Commons for that.
The bounding box of the png is always there and blocks what is behind even if it is transparent. I do not think that using z-index in this case would be practical.
Ok thanks will look into that.
