Hello, I have a problem with the slideshow.
Explanation: I have several "square" images in a slideshow and I would like which ones remain square regardless of the resolution or the device used, desktop, mobile, tablet... How to force the conservation of a ratio 1: 1 in all circumstances.
An example in the image but I have other resolution and other media or ratio and even more different.
For information: I have tried different configurations for several days with the height options etc.
Thanks for your help
Chris
