# React Native Web makes a disabled Pressable box-none, so its children take taps through a hidden parent: use inert

## Rule

If a hidden layer with pointerEvents="none" still takes taps on the web, look for a disabled Pressable in it; set the browser's inert on the hidden subtree instead.

## Snippet

```tsx
// before: hidden cards only set pointerEvents
<View pointerEvents={live ? 'auto' : 'none'} style={hidden}>{card}</View>
// after: inert on the web as well, which also takes the subtree out of focus order
export function useInert(inert: boolean) {
  const ref = useRef<View>(null);
  useLayoutEffect(() => {
    if (Platform.OS !== 'web') return;
    const node = ref.current as unknown as { inert?: boolean } | null;
    if (node) node.inert = inert;
  }, [inert]);
  return ref;
}
<View ref={useInert(!live)} pointerEvents={live ? 'auto' : 'none'} style={hidden}>{card}</View>
```

## Check

with touch emulation, tap the real Next and Previous arrows through every piece and back: at each stop every control of the card shown takes its own tap (here 62 of 62; 32 stops failed before).

## Applies to

react-native-web@>=0.21 <0.22

## I assumed

`pointerEvents="none"` on a hidden card takes its whole subtree out of touches, on the web as on a phone.

## What happened

a phone tap on Next did nothing from the 11th of 14 pieces on. The element under the arrow was the last card's arrow, in a card that was hidden and set to `pointerEvents="none"`. Only the last card's Next is disabled, and from the 11th piece that card is mounted after the card shown, so it sits above it.

## Why

read in React Native Web 0.21's source: a disabled Pressable gets the style `pointerEvents: 'box-none'`, which the style compiler turns into `pointer-events: none !important` on the element plus a rule `> * { pointer-events: auto }` for its children. The children's own `auto` beats the hidden parent's inherited `none`.

## The fix

`useInert` sets the browser's `inert` on a hidden card's content and on a closing sheet. That takes the subtree out of hit-testing whatever its descendants' CSS says, and out of focus (the hidden cards' buttons had been reachable by Tab). Phones keep `pointerEvents`.

## Evidence

a walk tapping the arrows 4 → 1 → 14 → 1 with phone touch emulation, light and dark: 32 stops failed before the fix (Next taken by card 13 from 11 of 14), 62 of 62 after (commit da8ecad).
