Need to make grid of HTML embed blocks automatically fit content items based on content's size

Hi there, I have a grid on a page with two columns, where we add HTML blocks to embed twitter-based testimonials.

Each tweet can have a slightly different height based on their length, naturally, and we’d like to make the tweets in each column fill in/adjust to the tweet block above it so that it’s a responsive masonry type layout (like a 2-column pinterest board).

I’m not a designer by trade, but know enough in Webflow to be dangerous - hoping this is a pretty simple fix/adjustment!

The live page is here: Trendy on Twitter

Thanks!
