This challenge wasn't that hard, but I was able to keep practicing Bootstrap. However, does anyone know how I can position the image better, since as you can see in the code the image is the background of a div, so I put a background-size: cover, but this makes the image on a tablet it stretches and looks bad and when the resolution is too small it cuts off. I tried with a background-size: contains and it looks better but the image is not cut but a space of the color remains!
