How to make swipe position uniform for all devices

I wrote a basic tutorial on element-relative swiping that may be helpful - the problem that you’re having is that your swipe is using absolute positioning, which is going to behave differently on devices with different screen sizes.

By supplying the element you want to execute your swipe on, you can define relative coordinates for your swipe. This should be enough to get you on the right track.

Thanks,
