Just stumbled upon this cool thing while digging through some specs! Turns out HTML and JS have a built-in modal system using the popover attribute. Imagine being able to stack contents or accomplish tasks without needing external libraries - talk about improving UX on desktops AND mobiles, right? But here's the kicker: most devs don’t seem aware of this yet! So let me know if you guys have tried it out and what your thoughts are. I can't wait to give it a shot myself soon :)
