Is there a way to check Viewport Height for mobile design?

Hello all,

General purpose question here… Is there a way to check the viewport height for mobile design in the editor? I’ve searched far and wide and can’t seem to find an answer to this question… Since mobile-first design is best practice and there are a wide array of viewport heights for mobile devices I feel like this is something that’s rather important… I’m using an image that is positioned absolutely in my mobile design so I’m wondering how the hell I’m going to make this work if I can’t see the browser viewport height while designing???
