Loads custom CSS on WordPress Login Pages, Admin and Front-end via the admin interface. Can be used with WordPress single install and WordPress multisites.
Custom LAF CSS is very useful on multisite networks. Admins can customize the look and feel of the network and add CSS for the entire network. Adding CSS to the front-end via this plugin is handy when common features need styling and you are not sure which theme the user will be activating.

<ul>
<li>Loads custom CSS on Login, Admin and Front-end pages regardless of the active theme.</li>
<li>CSS for Login, Admin and Front-end is separately saved and used. </li>

<li>Translation ready.</li>
