Is there an Ionic 2, ionic serve way to view tablet resolution?

Currently I only know 1 way to view my app in the tablet resolution, which is by doing ionic emulate ios --target="iPad-Air-2".

I’m having trouble debugging some CSS issues in iOS, but I can’t inspect the elements in the iOS emulator.

Why not use ionic serve and then just resize your browser to the correct size?
Or debug in the emulator using safari inspector like explained at https://ionic.zone/debug/remote-debug-your-app#ios?
