Greetings,
Everyone might already know this but I just figured it out. Sometimes when I want to use the Confetti Spray style, I don't want an image in the background, only text. So I have been putting in a dummy image and just reducing the opacity to '0' and then put in the text.
But I discovered all you have to do is to reduce the opacity of the last item in the style to '0' and add your text.
