Interactive Video - Add background image to interactions
When adding interactions to an interactive video, like multiple choice question, fill in the blanks, etc., we get a plain white background to the interaction. I would like to add an image that will serve as a background for the interaction, or let me customize the white background with some pattern, or make it half transparent. It will also be helpful if we can set the font and size of the text for the interaction.
BTW: I'm a C# developer and don't know much about css, but I can try to make the white background half transparent, if you can give me some directions. When I have changed this css:
background: rgba(255, 255, 255, 0.9);
to rgba(255, 255, 255, 0.5), it had no effect. FireFox completely ignore the alpha channel.
