Transparent background for titles and subtitles

[joaomaroco]

Hi there,
Right now the titles and subtitles in YAML have a white backgound... Is ist possible to remove the white background and leave it transparent like in the beamer metropolis theme?

Thanks!

Certainly. As I don't use this project right now/anymore, custom CSS is your friend. Identify the respective class and overwrite it, that should do it.

If you wanna patch it in the project directly, you can also open a PR.
