A child theme simply inherits the functionality of any WordPress theme. Child themes enables you to edit or add new functionalities to main parent theme without digging inside its code files. The features added to a child theme overrides the features of main theme and hence it is the safest way for adding custom CSS, custom hacks and the best thing is that the code added to a child theme doesn’t gets lost after new updates.
Child Theme Wizard is the new WordPress plugin that lets you easily generate a child theme (from any theme) in just one click and lets you customise its options. The plugin provides you a one step wizard ;-) which lets you create a new child theme without any need for additional tools and coding as everything works right from the WordPress admin interface.
