Smart CSS Auto Loader is a WordPress plugin designed to facilitate the loading of additional CSS files without altering the theme. Users can place CSS files in a specifically named directory called 'cssautoload', which can be located in the wp-content directory, the theme directory, or the child theme directory. The plugin recognizes only files with the .css extension, ignoring others, and supports CSS for various media types by allowing users to organize their stylesheets into subdirectories corresponding to the desired media type.

As of October 2023, development and support for Smart CSS Auto Loader have been retired, meaning no further updates will be provided. However, the plugin can still be used as long as it functions properly for users. Importantly, the plugin does not set cookies, collect or store any data, nor send information to external servers, ensuring a straightforward and privacy-conscious approach to managing stylesheets.
