Change weight of CSS file loaded in custom module with #attached?

Question

Im working on a custom module which loads a CSS file:

$content['#attached']['css'] = array(
  path_to_theme() . '/new.css',
);

How can I change the weight of the file so that its loaded after the other CSS files? I thought it would be something like this:

$content['#attached']['css'] = array(
  path_to_theme() . '/new.css',
  'weight' => 1000,
);

Or this:

$content['#attached']['css'] = array(
  path_to_theme() . '/new.css',
  '#weight' => 1000,
);

Answer 1

You want something more like this:

$content['#attached']['css'] = array(
  array(
    'data' => path_to_theme() . '/new.css',
    'type' => 'file', 
    'weight' => 1000,
  ),
);
