How to get box-shadow on left & right sides only

Question

Any way to get box-shadow on left & right (horizontal?) sides only with no hacks or images. I am using:

box-shadow: 0 0 15px 5px rgba(31, 73, 125, 0.8);

But it gives shadow all around.

I have no borders around the elements.

Answer 1

box-shadow: box-shadow: 0 5px 5px 0 #000;

It works on my side. Hope, it helps you.
