Did you know that you can mirror any library item and sync it across your website? Each library item can be made “Global.” Global modules are synced and mirrored wherever they are placed. Whenever a Global module is altered, it updates automatically on all of the pages you have added it to! Cool huh?!
Take for example, you could create a Global section that is added to the footer of every page on your site. Update that Global Section once and have the footer of your entire website updated instantly.
