Float Element to top of Container

¡Hello people of Webflow!

I’m trying to create a blog of interviews on Webflow, and I’m having some trouble working with a specific layout trick.

Let’s put it like this: within a blog page there are several Questions (Containers) that include a Title (H1), some Paragraphs (p) and a Cart (Lightbox) with images.

I want the text elements to float to the right of the Container, consecutively, and then have the Lightbox floating to the top left of the parent Container.

However, for some reason, the Lightbox element will only float to the vertical top of its current position within the Question – NOT to the top of the parent element. I can achieve this with absolute positioning, but that is not my goal, because that would get it out of the flow of the page, remove bottom margins and the like.

I’m pretty sure the solution to this should be fairly simple, but I haven’t been able to wrap my head around it.

Thanks in advance!

Here is a quick image to see what I mean: the left Lightbox will not go over the invisible line which constitutes its position within the Question.
