Product preview card component solution, using SCSS and Flexbox

Hello all! This was my first time using SCSS, and while this simple project could've easily been done without it, I am wondering if I could've used it even better for this project? I only used SCSS to make my variables and simple nesting easier.

Also, I wonder if the accessibility of the page could be improved? I think I did a pretty good job with it, but I am sure I still have a lot to learn.

And lastly, would a library like Bootstrap or React make the job easier for a web page like this? Or is it not worth using them for such a small project? I am only just getting started learning React, and I'm wondering about the scope of its usage.

Thanks for any and all feedback!
