Can I control the look of the < and > arrows in a slideshow?


I would like to use the Slideshow feature on sort of a profile picture for different services. So these pictures are not very large. Under 400px in diameter on a current standard resolution.

The navigation arrows appear pretty giant (also the light/dark setting doesn’t appear to make a difference). The placement from the left/right edge also changes pretty dramatically when I switch to smaller resolutions / mobile view.


Is there any way I can control the look or size of these via CSS? Use a different icon, or size the arrows down at least? That would be really helpful.

Thank you for your help!
