'How to make navigation toggle button above body content view in html?

I have my navigation toggle to hide and show side navigation

But if i zoom in the screen, The navigation button will go behind the body content view.

.navigationButton{
    display:inline-block;
    position:absolute;
}

I want to make the navigation button show above the body content view.

Try to use z-index to navigation button but it won't work.

How to solve this issue?

enter image description here

EDIT Navigation button position is above breadcrumbs. but below row class
