Happy Friday, everybody!

Our library recently got a shiny new, responsive-esque website.
<http://langsdale.ubalt.edu>  The reference librarians frequently zoom in
on our homepage during class instruction, and have noticed that after they
zoom in a bit, our homepage switches from desktop to the mobile layout.

Is there any easy way around this?  In other words, is it possible to fix
the site so that, if a user is on a desktop/laptop, zooming in on the
homepage will *not* flip the user over to the mobile layout?

Thanks for your help!
