Is there a way to code or label the images to be arranged/coded in a certain order when downsizing to mobile? I've created a layout that I love for desktop but when it downsizes for mobile, the images go "out of order" from my intentions.
If you're using a multi-image block, the images in the block will be stacked on top of each other in the mobile view, with the left image on top of the right image. To prevent this you will need upload the two images as a single image, by either using a photo editing program to combine them or by taking a screenshot of the multi-image block, so the two images are side by side. Here's an example of how the that would look in the mobile view of your Black Friday campaign:
I hope this help! Let me know if there is anything else I can assist you with!
