Slideshow multiState with transitions and controls

Hi everyone, I have implemented the X Stream ‘Slideshow with Multi State Box’ (see YouTube Tutorial)

But I have two issues that I need to fix:

  1. Better ‘smooth’ transitions between the ‘States’: at the moment there’s a ‘snap’ when the next slide appears, the title can have a fade in, but the background image starts from white (or background) if I apply a fade or any transition the the background image itself.

  2. Controls Navigation: is anyway to have two arrows for slide next or previous?

rightSliderBtn . onClick (() => { slideRight ();}) leftSliderBtn . onClick (() => { slideLeft ();})

Can anyone help me out? it shouldn’t be that difficult! Any Velo Expert could help? Thank you!
