Responsive Product Preview Component With SCSS And HTML

This was a pretty interesting project from the start. I have been currently learning about using grid and flexbox. I tinkered around with both grid from the start and later decided flexbox is probably the way to go with this one. I have had a problem im not sure why the button at the lowest breakpoint would not width 100% on google chrome but was working perfectly in firefox browser. Im not totally sure if the breakpoint and media queries was the most reliable way to achieve this result. I am open for suggestions on thing that could be fixed or change.
