Need to format the way posts are being pulled in on rss feed

Hello,
I am using the feeds plugin to pull in posts from Substack. I have modified the feed with this css. The first two increments format the text as you can see. By default the theme seems to make the thumbnails square so I added the third increment in the css to preserve the original aspect ratio of each of the thumbnails. You can see the result here: https://sethledermanmd.com/opinion-pieces/

But…I need the spacing above and below the individual poqststo be consistent, you can see that the sauce below the thumbnails is larger on the ones which have thumbnails which are horizontal because the grid seems to have the same overall depth for each post. Is there a way to have them pull in with a consistent amount of space below the thumbnails and also make he spacing above a little less in height?

Thanks so much.
