When should I use a Block Pattern?

If you want to apply the layout of several blocks, including styling choices, throughout your site in multiple locations, a WordPress block pattern will help. The intention is that content creators can apply your block pattern and swap out the images, text, or other assets to fit the context of where the pattern appears.

Differentiating between synced and non-synced patterns

When you have created a special design you want to keep and reuse, you can save it as a pattern and specify whether to sync it or not. A synced pattern was previously referred to as a Reusable block and changes to a synced pattern will apply to all parts of your site where the pattern has been added.
