Re: [csswg-drafts] [css-backgrounds] Add a 'hairline' border-width value (#3720)

@AmeliaBR Yes, I could. But when I viewed on Chrome/Safari/Firefox/Opera Mini on my iPhone XS Max, as @bradkemper has pointed, all values that less than 1px are rounded to 0.25/0.3px (maybe 1 device pixel). Based on this, I think using media queries to check the screen resolution is also not useful. Because it seems 
 none of the browsers have yield the control to us for how many device pixel one fractional px value could be snapped to.
