Let us introduce you the perfect time-saver: saving an element as global. When a layout is saved as global and you include it in multiple pages, whenever you make a change to it on one page, it will mirror instantly across all the other pages its placed on.
It is very useful to make a row, module or section global if you need to use it repeatedly on a number of pages. A good example of its convenience is the footer section: if you want a footer to always show on all your pages, save it as global and place it in all the relevant pages of your website. Now, anytime you change the section styling, on any of the pages, it will sync to every single page where you placed it.
Save an Element as Global
Add to the Library as Global
To save an element as global check the Make this a global item box, when saving an article to your library.
Identify Global Items
If you are editing an item, and the color of the tabs in the settings pop-up is green, then you know you are editing a global element. This way, you know that any changes you make will update on every page that item is included on.
You can also check the All Layouts menu screen, and identify global items in the table under the Global column.
Use selective sync with global modules
You can also use selective sync to update only a part of the styling across all pages. For instance, you have a header replicated on multiple pages where you want to keep the styling but wish to create unique titles for each. By using selective sync you can mirror only the styling, keeping the titles different.
