'Less' syntax highlighting in Geany

I'm using Less CSS (PHP version). I'm also using Geany on Linux. Is there a Less syntax file for Geany out there, or how I can go about editing the CSS one to suit Less?

This should work. Just update your configuration file filetype_extension.conf.

1. Open ~/.config/geany/filetype_extensions.conf
2. Change this line: CSS=*.css; to this: CSS=*.css;*.less;
3. Save configuration file.
