XF 1.3 Is there an existing media screen width variable defined?

[motowebmaster]

I've implemented a adaptation of responsive banner ads that appears to be working well. I'm saving some code an screensize queries by setting it once in javascript.

Is there an existing screensize value that I can re-use in an xenforo template, so that I can remove my added javascript and reduce screensize queries further?
