The first thing you'll notice once you select a page in the Layout & Design tool are the buttons at the top. Use the action buttons in this toolbar to navigate your way around the Layout & Design tool.
Devices
You can see how your template adapts to different devices by clicking on the different device layouts. Mobile, tablet, and desktop are displayed in that order.
Undo/Redo
These two arrows allow you to undo or redo changes quickly and easily.
Save
Save all your changes and push them live to your site.
+ Add Element
Use this action to add what we call "elements" (e.g., image placeholders, ad code, custom HTML) to the rows and columns of your site layout.
A/B Tests
This button shows you all of the A/B tests that've been created for the page you're in. And if you've never created an A/B test before, clicking this button will create your first B-test layout.
Cut/Copy/Paste
Easily cut, copy, or paste elements from one page to another using these action buttons. These help you avoid having to restyle the same elements over and over again across your site.
