Note: I have updated this plugin with an admin interface. You can read more about the plugin on the WordPress plugin directory. The following write-up applies to version 1.0 of the plugin. Download links are available at the end of the post.
If you want to add CSS on the login pages and front-end, in addition to the Admin side, use my Custom Login Admin Front-end CSS plugin. It supports multisites as well.
I had written on how to load CSS on the admin side before. This involved adding the load function into the functions.php of the theme.
Recently a need arose where the CSS had to be loaded irrespective of the theme being used, on a multisite network. So the function took shape as a plugin and I have my first WordPress plugin up in the extend.
Admin CSS MU
Admin CSS MU simply loads a CSS file. All your custom CSS can go into that file. I think the best use case for the plugin would be as a mu plugin, since it wouldn’t probably need an update ever (and hence the MU in the name).
Installation Instructions:
To use as a normal plugin in WordPress single install and Multisite.
- Install the plugin through the WordPress admin interface, or upload the folder /admin-css-mu/ to wp-content/plugins/ using ftp.
- Move (or create) custom_admin.css to wp-content/themes/ folder. (it should look like wp-content/themes/custom_admin.css)
- Add the custom css you want into custom_admin.css.
- Activate the plugin via WordPress admin interface. If it is a Multisite, preferably Network Activate it.
To use as a Must Use (mu) plugin for WordPress single install and Multisite.
- If you don’t have already, create a folder /mu-plugins/ in /wp-content/ directory on your server. (it should look like wp-content/mu-plugins/)
- Upload the file (just the file, not folder) admincssmu.php to wp-content/mu-plugins/ . (it should look like wp-content/mu-plugins/admincssmu.php)
- Move (or create) custom_admin.css to wp-content/themes/ folder. (it should look like wp-content/themes/custom_admin.css)
- No activation is necessary. MU plugins are always active and can only be deactivated if you delete it. No auto-updates are available though.
