Issue with aligning slider images to grid

Hey there! :slight_smile:

I’ve got an issue concerning my slider. I created a slider thanks to the post from @sabanna (Unique slider layout? - #3 by daniel_cleayweb)

It works well. However, I would like to align the left and right image (so the previous one and the next one) to the grid of my navbar. (see images in annex)

How can I keep them in the same place?

Some help would be really appreciated! =)

ps.: the designer preview and the online preview aren’t coherent, however webflow is already having a look on that.
