I'm adding a node to the toolbar and wish to tweak the css a bit. I don't have any external CSS files and I'm echoing the CSS using the wp_head action hook. Is there a similar action hook that I can use to echo the CSS everywhere? Both front-end and admin area?

The alternative to wp_head action in admin area is admin_head. But, if your CSS depends on another stylesheet, you should use wp_add_inline_style() function hooked to admin_enqueue_scripts action.

  • And is there a single hook that will allow me to echo in both front-end and admin area? Commented Oct 12, 2016 at 7:37
  • A hook to echo in <head> in both sides ... I don't think so, but I'm not 100% sure.

In addition to wp_head and admin_head there's a separate hook for the login screen, called login_head if any custom code is needed there.

( This should have been a comment, but my reputation is still to low. )


You could always just hook into both of them from the same function:-

function wordpress_stackexchange_242372()
    // Your code here
add_action( 'wp_head', 'wordpress_stackexchange_242372' );
add_action( 'admin_head', 'wordpress_stackexchange_242372' );

Pretty sure that should work :)
