如何在functions.php中设置类的样式

Question

[![enter image description here][1]][1]I added I some classes to my functions.php like so:

add_action('admin_menu',
    'wpso_custom_links_admin_menu');

function wpso_custom_links_admin_menu() {
        global $submenu;
        $submenu['index.php'][] = array('Link One', 'read',
            'https://www.example.com/', '', 'jobs-dashboard');
        $submenu['index.php'][] = array('Link Two', 'read',
            'https://asdf.com/', '', 'events-dashboard
            ');
        }

Then I added css:

. jobs-dashboard {background-color: green;}

Didn't work. Why not?

It looks like you are using your themes additional CSS option, which is typically for front end CSS changes.

To add CSS to the admin area you can use the admin_head hook in your functions.php.

add_action('admin_head', 'my_custom_css');
function my_custom_css() {
  echo '<style>
    .jobs-dashboard {background-color: green;}
  </style>';
}
