Profile card component (desktop desigh only)

Hello, everyone! I'm a rookie in that whole sphere, so do not wait a lot. I didn't do the mobile version because I have no idea how even. I found several colors, but couldn't get why there were three of them so I used only one, which was not grey ( another two ones were). I am not sure that my code is right, but I would appreciate your helping and notice! Thank you. P.S. I don't know why, but if you check my code you'll see, that I changed display properties for 2 div tags (sphere_1, sphere_2) to inline-block, but it hadn't been applied. Why?
