Our Commentary ​

I love a good CSS deep dive, especially when it covers properties that aren't always in the spotlight. box-decoration-mode and text-combine-upright are particularly interesting for advanced typography. It's a reminder that even seemingly minor CSS properties can unlock significant design possibilities. We often forget the power hidden in the spec.
