Hmm, I’m not sure it’s possible to set it so it always matches the height of the item to the left, especially with new articles. You can target that specific post with CSS and try to tweak some things (padding/font sizes etc..) but it won’t be perfect.
I’ll keep thinking about a solution and will post back here if I think of one.
Cheers. Our stories will be updated all the time, so I want to try and avoid any individual story CSS work. I’ll keep having a look as well and will update if I find anything.
