How to create a pulsating button
My goal: to create a button which at the end of the audio starts to pulsate (i.e. gradually changing its color from blue to red several times), so as to indicate that the learner may proceed to the next screen.
I would like to use a smart form as a button, because you can easily label the button / smart form with a caption text.
I tried to accomplish the pulsating effect with the color effect "hue variation" (or called something like this - I use the German version). My problem: The color effect doesn't only change the fill color of the button (as intended) but as well the text caption (which should stay white). Any suggestions how to change only the fill color, but not the text of the button?
Best regards
Jan
