Looks like the link to your read-only site is broken but I had a look at the reference and it looks like there are 15 full hight columns that have mouse hover triggers, “When hovering over this column, this image should go from 0% opacity to 100% opacity” and when hovering out of the column the image goes back to 0% opacity. And the images look like they are 100vw and 100vh.
And if you want to create a custom cursor this is a good resource: https://webflow.com/blog/custom-cursors-guide
Hope this helps!
Hey, thanks for this information – that helps a lot!
