Hi, On my Sessions page, I am having trouble making arrows display on the side of a carousel rather than underneath it on mobile, I would also like to use a custom image for the arrows. I have managed to find code for this on the forums for this however I cannot change the arrows to something custom. I think the custom code I found online has broken something on my half term camps page as the circle images reveal and then revert to being square? any help would be greatly appreciated as I am new to all of this.
