On Mobile Chrome, it's basically unusable. Scrolling ruins the back button. Everything is horizontally smooshed. The scroll snapping is broken to the point that it snaps me to places I've already scrolled past. The animation on the tabs is visually confusing and seems to necessitate the tab is a fixed height that scrolls. Tooltips and scrolling break each other. The forms don't accommodate mobile widths unless you manually use the wide option. Even then, they have no border. The checkbox looks checked when it's unchecked because it has a dark background. The active and focused states on buttons aren't differentiable from disabled (opacity versus gray?). Sorry, but this is just not good to use.
Thanks for the great feedback. The back button navigates to the previous slide. The tabs take the height of the tallest tab, I thought that was normal. Tooltips should hide on scroll, indeed. The forms have border when --nui-border-color and --nui-border-size are set. The focus indicator is the native style on purpose to avoid confusion. Thanks again.

Nobody comes to this page thinking it's slides. There's no expectation it would or should work like this. It adds a feature that makes the site harder to use.
