Link to the challenge:

your box-shadow is not exactly the same as the one they gave you. You have this:

box-shadow: 0px 10px 10px rgba(0,0,0,0.19), 0 6px 6px rgba(0,0,0,0.23);

and they want this:

box-shadow: 0 10px 20px rgba(0,0,0,0.19), 0 6px 6px rgba(0,0,0,0.23);

just fix that and you should be good.

And btw, could you explain what does “zero” stand for in this formula:
box-shadow: 0 10px 20px rgba(0,0,0,0.19);
0 -?
10px - offset-x
20px - offset-y
rgba - color

I am not 100% sure what the first zero is for, but it seems to make the shadow appear more blurred.
Usually the first parameter is the ‘inset’ parameter but that’s not the case here. Maybe someone else can figure this one out.
