Got this to work by adding the Image_Summary alternate. Now this
is fully responsive!
I add a new "Carousel" and then a new Projection/Query.
. But is this the way I should be doing this? If I publish the new Carousel, I get the normal detail layout: /Views/Content-Carousel.cshtml
Is it better to handle the rendering via projection or by adding an alternate?
Many thanks to @jtkech, who helped me along.
