Extending The GeneratePress Theme Framework...
The GeneratePress Framework provides a solid set of general design options through its premium add-on, but with the GP Extender Front-End CSS Builder/Editor tool you can take things much further!
Inevitably custom coding will become necessary during the web design process, even with GeneratePress. So when you need to dig into some CSS, PHP or JS coding it will all be there in your WP Dashboard.
GeneratePress provides solid tools for building out your page structure, but when you need to add site-wide customizations, or even go outside those page boundaries, you'll find GP Extender indispensable.
