I write a CSS snippet to create a transparent card. I think that combing it with the plugin is helpful to get a Prezi-like result. Using a transparent style, you can insert an image without any file name and create transparent cards on the part which you want to focus on the image. Then you can use the plugin to focus on the image and the cards.
The disadvantages are:
- You need to make the image large enough to get a better view
- It may be difficult to adjust the size of transparent cards as they cannot be seen.
