Hi there,

That's a very good question. In WordPress, Full Site Editing (FSE) allows you to design your entire site—including the header, footer, and everything in between—using blocks. Blocks are the components for adding content in the new WordPress block editor, enabling you to easily incorporate text, images, videos, and more.

For this new approach, your site will require a Block theme, designed specifically for compatibility with this new editor. Also, one thing to note here is that the traditional theme customizer is no longer present in this environment. Instead, FSE allows direct manipulation of site elements within the WordPress Block Editor interface.

The full site editing thing really changes the wordpress paradigm. It's a different mental model. I've had people reach out for help because it ends up being a wall for them. The communication/education aspect of it needs work.
