After install a high quality WordPress theme, you find it has a Theme Option page. Per theme, developer will make their own Option page (functions, features, layout …) so it can not be compatible with your theme or others. Let’s me know what’s you feel when changing to new WordPress theme then you start learning again to re-configure WordPress and you’ll see why that’s a bad thing for WordPress publishers. That’s why I always disliked about theme settings pages was how vastly different they would get.
The Theme Customizer was introduced since WordPress version 3.4 then it’s become a relatively new way of WordPress Themes to provide you with options. It allows for an editing environment where theme options can be tried by the administrator before being applied to the live site. Currently, I’m using WordPress Theme Customizer as my default theme options instead build my own or using other theme options way.
In this tutorial, we will look at exactly how this feature can be added to a theme and I show you how to create your own classes to extend the controls to make your own Customizer Custom Controls, since not all fields and requests are in the core already. You can access existing solutions of the community or create your own classes.
