Nested slider navigation problem on Safari

[vktra]

I've nested several sliders and it works great overall, except on Safari where the navigation arrows only appear after a resize of the window or after the first slide has gone through (by drag and drop or using the keyboard). I forced all the css properties of the arrows (swiper-button-prev and swiper-button-next): opacity, display, z-index... But nothing to do, it still doesn't work.

Thanks in advance.
Cheers.

Try using height: 100vh, using height: 100% is not a good candidate for nested relative elements

Thanks for the advice but unfortunately it doesn't seem to work...
