Stats Preview Card Component Challenge builded with basic HTML and CSS

What's up guys

I've completed the challenge and both version seem to work. But Is not responsive when I change manualy the size of the window. Any hints?

Another doubt is that to achieve the purple color on the image I put a purple square at the top of the image. Is there a better solution? I've tried to use the filter property but I couldn't achieve the results that I want.

Thanks in advance.
