How do I get them the same height on smaller screen? 
They are in a grid. Would be nice to be able to set the minimum height per device @dan
There’s many ways to fix that, you could change the text size or set specific heights on smaller screens…
If you can share just that section in a test project file and upload it to Elements Cloud, I can take a look at what’s going on and tell you how to fix it 
You’ll need to use the following code in the Advanced CSS section of the Card Flip component:
[&_>div]:h-full
Here’s a video showing how this works:
Hope that helps
