With <a href="https://github.com/pixelgrade/customify" rel="nofollow ugc">Customify</a>, developers can easily create advanced theme-specific options inside the WordPress Customizer. Using those options, a user can make presentational changes without having to know or edit the theme code.
This plugin is primarily intended to be used together with <a href="https://wordpress.org/themes/author/pixelgrade/" rel="ugc">Pixelgrade themes</a>. So the best way to get acquainted with it’s capabilities is to study the way <a href="https://github.com/pixelgrade/rosa2-lite/tree/master/inc/integrations/customify" rel="nofollow ugc">one of Pixelgrade’s themes</a> integrates with it.
