In lieu of a screenshot, her is what the java console at http://mightygrip.com/events/user/add reported:

“Consider using ‘dppx’ units, as in CSS ‘dpi’ means dots-per-CSS-inch, not dots-per-physical-inch, so does not correspond to the actual ‘dpi’ of a screen. In media query expression: print, (-webkit-min-device-pixel-ratio: 1.25), (min-resolution: 120dpi)
