Hi! I'm curious if there is a way to make grouped images transparent at the top and bottom edges of the group. Right now, I have 24 thumbnails that is grouped up and they are controlled with a timeline that slides through the images. However, I want the top and bottom (the timeline goes vertical) to be faded out to zero. I did the easy trick with an image that is fading from transparent to the background color, but because the background is switching to the enlarged thumbnail behind it, the background color will be impossible to copy into the fading image.
I tried some css without success.
Here is an illustration on what my problem is:
