I removed the option to limit the number of levels. Use the now supported custom navigation if you would like to change your top level links.
Why not compose your own css-layout file and paste it to the layout folder of the dkret3 theme.
Try combining the two layout files (Sidebar-off.css and Fluedelity.css):
/**
* Creates a one column fluid layouts with no sidebars
*
* #Content
*
* @since 3.6
* @package dkret3
* @subpackage CSS
*/
/* Get layout CSS */
@import url('../css/1c-layout.css');
#wrapper {
max-width: 1200px;
min-width: 600px;
width: auto;
}
Better practise is to add the my-dkret3 child theme and make the needed changes there.
