Minamaze_Pro/styles vs Minamaze_Pro-child/styles

Hi
this code:

@media only screen and (max-width: 1205px) {

	#header-logos-nr {
		display: none;
	}

	#header-logos-responsive {
		display: block;
		width: 100%;
	}

	#header-logos-responsive_3 {
		display: none;
	}

}

@media only screen and (max-width: 940px) {

	#header-logos-responsive_1 {
		display: none;
	}

}

@media only screen and (max-width: 768px) {

	#header-logos-nr {
		display: none;
	}
}

Is workin without problems inside this path: ” Minamaze_Pro/styles”

but if I use the same code into the child theme it is not working; the path into the child theme is: “Minamaze_Pro-child/styles”

Please your help
