Note that while container queries are available in modern browsers' most recent versions, it is still very fresh, with broad support landing in September, and Firefox support just last month: https://caniuse.com/css-container-queries

If you use them, you'll need to show outdated browser warnings for basically all browsers older than September 2022. Your site will be horrifically broken without container query support.

I'm investigating if we want to even do that at my job. That's a pretty steep cost.
