I am making a simple portfolio site and for my main page I basically have a large square made up of smaller squares. I want the user to be able to click the squares and have them disappear so they can create a design. I am stumped. I tried just trying to make the squares buttons and have the down state with the square turned off or 0 opacity...but when I run the project it only goes white/gone if I click and hold. Ideally it needs to have the square disappear and stay gone... I'd appreciate any help. Thanks!
If your squares are raster files they wont ever be transparent as you suggested.
