Child Theme CSS No Effect | TwentyFifteen

Hi All,

I have made a child theme of twentyfifteen that works fine. But when trying to move the sidebar to the right the code I enter in the child themes CSS seems to have no effect. Here is what i have in the childs style.css

@-ms-viewport {
	width: device-width;
}

@viewport {
	width: device-width;
}

@media screen and (min-width: 59.6875em) {
	.site-content {
		float: left;
		margin-left: 0px;
		width: 70.5882%;
	}

	.sidebar {
		float: right;
		right: 0;
		margin-right: 0px;
		max-width: 413px;
		width: 29.4118%;
	}

	body:before {
		right: 0;
		left:auto;
	}

	.site-footer {
		margin: 0 0 0 6.1%;
	}

}

No idea why this has 0 effect. You can see the site at https://kickassd.com

In the childs functions.php I have:

<?php
add_action( 'wp_enqueue_scripts', 'enqueue_parent_styles' );
function enqueue_parent_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
}
?>

Any help much appreciated!
