        <pre>Please take a look at the following JSBin in Safa:

<a href="http://jsbin.com/hokayuc/53/edit?html,output">http://jsbin.com/hokayuc/53/edit?html,output</a>

In the above code I am defining a custom element `card-swiper`. In the template for this element, I am using a &#64;media query to control the `flex-wrap` property of my `.slot-container` class.

The &#64;media query is completely ignored in Safari 10, Safari TP, and Webkit.

Chrome functions as expected.</pre>
