Admin CSS MU

Description

A simple plugin that lets you add your custom CSS to style the WordPress Admin. Works with WordPress single install and WordPress multisites.

Version 2.0 is updated wtih an Admin interface and can be found in Appearance > Admin CSS MU

Admin CSS MU uses CSSTidy to clean and optionally minify CSS. CSS is only minified while using it. The editor always shows un-minified CSS for easy editing.

Note: If you want to easily add custom CSS on your Login and Front-end as well (along with WordPress Admin), use my Custom Login Admin Front-end CSS plugin instead.

Installation

To use as a normal plugin in WordPress single install and Multisite.

1. Install the plugin through the WordPress admin interface, or upload the folder /admin-css-mu/ to /wp-content/plugins/ using ftp.
2. Activate the plugin via WordPress admin interface. If it is a Multisite, Network Activate it.
3. Go to WordPress Admin > Appearance > Admin CSS MU and add the custom CSS you want.
4. For Multisites, the settings page will be in the Appearance > Admin CSS MU of the main site. Only network admins can add/edit CSS.

FAQ

Can I try the CSS sample from the screenshot?

Sure! To change the background colour of the dashboard add this and save.

#wpwrap {
    background-color: #5f5f5f !important;
}
body, h1, p {
    color: #f1f1f1 !important;
}

I found this plugin very useful, how can I show my appreciation?

I am glad to hear that! You can either make a donation or leave a rating to motivate me to keep working on the plugin.

Nice, but not works with complex css

It do simple css but can’t handle media queries or multiple selectors. Better it simply add styles than making them pretty, I bet tidying is messing all

Works great. Thank you.
