Addition to your code: prevent gap while adminbar is hidden

Hi Alex,

thanks for your plugin.

I added this code to your plugin to hide the “gap” at the top of website/dashboard while the admin-bar is hidden:

// Remove the top margin/padding of the admin bar, preventing a "gap" at the top of the page
function remove_topmargin_front() {
	echo '<style type="text/css"> html { margin-top:0px !important; }';
	echo '* html body { margin-top:0px !important; }</style>';
}
add_action('wp_head', 'remove_topmargin_front',1000000);

function remove_topmargin_admin() {
	echo '<style type="text/css"> html.wp-toolbar { padding-top:0px !important; }';
	echo '</style>';
}
add_action('admin_head', 'remove_topmargin_admin',1000000);
