vertical menu bar css

Question

i would like to customize my dashboard navigation menu to vertical styling. i needed to find the <div id="adminmenu"> but there are tons of CSS inside /wp-admin/css

also, does changing the CSS adminmenu is the correct approach of changing the <ul> into vertical styling?

Answer 1

You shouldn't hack the Wordpress core. You can use a hook to do it. Example:

function dashboard_vertical_styling() {
   echo '<style type="text/css">
           #adminmenu { something goes here; }
         </style>';
}

add_action('admin_head', 'custom_colors');
