Updated solution to Product Preview Component

The overall design looks fine but I found some issue with the responsiveness your design seems to breakdown when the screen size is decreased I am not really sure what is causing the issue but I am doubting the use of your media queries and the way you have set the width and height of different elements I guess it would be better to set the width on the #main-div as a max-width and another thing is it is recommended to set font-sizes in rem/em. That's my suggestions ✌️.
