I’d like to display some content based on the screen width.
Quasar has window width related css classes for that.

Displaying the content whenever the breakpoint is above md works:

 <div class="gt-md text-grey-11 text-h1">Hello</div>

But how do I use this conditionally?
With tailwind we can use the breakpoint as a prefix, like:

<div class="text-grey-100 sm:text-red-100"></div>

How to do that with Quasar?
