(SOLVED) Weird Webflow slider behaviour

Hi there,

I was wondering, what I could be missing with the slider I just built within my project.
It is a simple slider with three slides pulling their background image from the CMS.
Everyhting works fine, except there is a weird border all around the images.

I made a screenshot of the transition, hopefully you’ll understand what I mean :slight_smile:
Thank you for your help !

EDIT: somehow found out it’s a webflow preview issue. All good on the published site :slight_smile:
