Page Builder Wrapper Elements
There are some of the wrapper element call section and column. If you want the element like team , blog to show on 1170px grid then you need to place those elements inside the column wrapper and then by using the + / – button on the left top of the column wrapper you can control the size of the wrapper easily.
If you want the element go for the full width then drop the element from the page builder without using any wrapper.
From section wrapper you can manage the background color , image of the section easily.
Page item and page class allows you to enter the custom css class or id which contains your own css styling of any section you want to have.
