Expected behavior

expect images to be zoomed smoothly on Safari

francoischalifour commented 3 years ago

The image in question is very big (4000x2667px), which is likely why the transition is not smooth on mobile.

You can use the srcset attribute on your images so that the browser pick the right resolution based on the screen.

@francoischalifour it's pretty smooth on android mobile, only went wrong on Safari on iPhone or Mac
