Responsive product preview card using BEM convention

This is my first project where I used Block Element Modifier (BEM) convention and Mobile-first workflow. In my opinion, the project was too small for experience the benefits of BEM but it was a good opportunity to get familiar with the concept.

In desktop view at the bottom of the image I could see 4pixels of the background. After some research I managed to resolve it by setting the display to block. Moreover, previously I followed desktop-workflow and now it was more difficult to do the other way around, especially the alignment of the screen sizes.
