Responsive page of product preview card using HTML5 and CSS3.

I had a lot of difficulty when styling the project, as some elements did not have an acceptable result and similar to the image of the challenge. It could also be because I started styling the PC part and not the Mobile part, but in the end everything worked out and I realized that I need to be more careful and careful when styling.

Please let me know what you think of my code and give me suggestions for improvements. Thanks :)
