sharing icons alignment in mobile view

Hello Team,

I would like to place the sharing icons at the dead end bottomin mobile view.

I have enabled to vertically if screen size is less.. So naturally it is already at the button. However there are few inches of the background visible at the bottom. I want to make it reach the dead end. How can I make it ?

Regards,
Muthu.
