Specifically, how you use enqueueto create a hierarchy (ie dependencies).
When I tried using the example and following the format, I end up with the exact same styling. I assume I’m just using the dependencies wrong, but here is what I did when I tried doing it.
<?php
//Load Theme css//
function theme_styles()
{
wp_register_style('bootstrap-responsive', get_template_directory_uri().'/css/bootstrap-responsive.css', array('style.css'), '1.0', 'screen');
wp_register_style('flat', get_template_directory_uri().'/css/flat,css', array('style.css, bootstrap-responsive.css'), '1.0', 'screen');
// enqueing:
wp_enqueue_style('main', get_template_directory_uri() . '/style.css');
wp_enqueue_style('bootstrap-responsive');
wp_enqueue_style('flat');
}
add_action('wp_enqueue_scripts', 'theme_styles');
?>
