Media Query for all other orientation other than Desktop

Hello

Can you help me run a media query Custom CSS where I would like an element in the exact location on all orientations please.

The element is:
.vc_general.vc_btn3.vc_btn3-size-sm.vc_btn3-shape-square.vc_btn3-style-outline-custom {

And I've already set the margins for desktop version:
margin-top: -910px;
}

However I need this element in exactly the same place on all other versions, you can find the custom code here: Appearance>Customize>Custom Code at the bottom

Support portal is open for your convenience

Thanks
