Hi Veronica, thanks so much for this! I managed to fixed the grid overflow issue, thanks for pointing out the potential causes.
As for the initial state in interaction, I tried the Page Load interaction that you mentioned, but there is a problem with this. I set the Thumbnail image as opacity :100 % upon Page load. But this creates another problem because it affects my hover interaction, the thumbnail wouldn’t fade out at all.
My default state for the thumbnail was already at 100% opacity in the style panel in my Design mode. Then in the interaction I also “Set Initial State” of this thumbnail at Opacity 100% too(see pic)
Is it possible to look at my set up and see if there is another way to fix this? Thanks so so much.
