Change position on mobile?

Hello,
I would like to change position of the hashbar by the size of screen or at least on mobile/tablet devices. I couldn’t find any options like that.

When I try to do it by CSS coding it racts strange.

.hthb-notification {
position: absolute;
bottom: 0;
}

When I use this code it’s trying to modify itself touch to bottom but also keeps itself on top and fills the screen with height. Tried to limit the height but didn’t respond also.
Maybe if I deselect the sticky option it would act better but I would like to ask what could be the best or better option to change sticky position by the screen size.

Thank you.
