Dear @Stefanie
there is not an official way to do this because the carousel adjusts to the grid from your LayGrid.
You could use CUSTOM CSS to make changes.
For example like here:
.col .lay-carousel-wrap { width: 80vw !IMPORTANT; }Now the carousel size adjusts.
With some more basic CSS magic you will be able to position the carousel better.
I hope that helped. Let me know if you need more specific help.
Best!
