I'm creating the graphics for the application for my thesis, but I'm experiencing problems.
I have icons that are empty, and at their click I would like them to become colored, and to re-click, I would return empty.
a kind of toggle click.
does anyone know how it could be done?
I probate with the click and overlay option, but then the icon is fixed to me in a point and when I scroll the page it doesn't stay where it was before and moves with the page itself.
