Product Preview Card Component

I would like the community to offer their opinion in terms of the code I wrote to replicate the component for this challenge, I believe it is solid code, but I would like to know about better practices if anybody has any better way of doing it.

I had an issue with the component's button element, for instance it is ok on large devices, but for some reason when the component is viewed on smaller devices, the button loses padding, if anyone could help me spot why I would be grateful as I didn't understand why it is happening.
