Extended Description

Interface for easily defining additional CSS (inline and/or by URL) to be added to all administration pages.

Ever want to tweak the appearance of the WordPress admin pages, by hiding stuff, moving stuff around, changing fonts, colors, sizes, etc? Any modification you may want to do with CSS can easily be done via this plugin.

Using this plugin you’ll easily be able to define additional CSS (inline and/or files by URL) to be added to all administration pages. You can define CSS to appear inline in the admin head (within style tags), or reference CSS files to be linked (via “link rel=’stylesheet’” tags). The referenced CSS files will appear in the admin head first, listed in the order defined in the plugin’s settings. Then any inline CSS are added to the admin head. Both values can be filtered for advanced customization (see Advanced section).

    return $files;
}

Frequently Asked Questions

Q. Can I add CSS I defined via a file, or one that is hosted elsewhere?
A. Yes, via the “Admin CSS Files” input field on the plugin’s settings page.

Q. Can I limit what admin pages the CSS gets output on?
A. No, not presently. The CSS The CSS is added for every admin page on the site.

However, you can preface your selectors with admin page specific class(es) on ‘body’ tag to ensure CSS only applies on certain admin pages. (e.g. body.index-php h2, #icon-index { display: none; }).

A. No, not presently. The CSS is added for any user that can enter the admin section of the site.
