How can I override the admin-bar so that it matched the style of the backend admin area of Wordpress? Should that disable the default and clone the admin-bar.css and modify that file is good idea?

You can override admin-bar with this function, don't need to mess with admin-bar.css.


  1. Write your css
  2. Put inside the function (given below)
  3. Add this inside functions.php

    // customize admin bar css
    function override_admin_bar_css() { 
       if ( is_admin_bar_showing() ) { ?>
          <style type="text/css">
             /* add your style here */
       <?php }
    // on backend area
    add_action( 'admin_head', 'override_admin_bar_css' );
    // on frontend area
    add_action( 'wp_head', 'override_admin_bar_css' );

    +1 but on wp_head you should probably check first if the admin bar is displayed at all, to prevent the CSS being added for not logged in users Jul 16, 2018 at 4:55

    Thanks @MarkKaplun, added the condition to check if admin bar is displaying. Jul 16, 2018 at 5:07
  • Could you actually explain what the different parts of your solution do? What is "backend area" and what is "frontend area"?

  • @posfan12 the backend area is the dashboard and the frontend is referring to the web page previews portion. Everything is self-explanatory, not sure what exactly is unclear for you. Apr 3, 2021 at 15:21
