By default, all our header builder’s elements have margin 10 pixels from left and right. So in a sum, there will be 20 pixels space between all of them to make it look clean. But there are may be some situations when you need to increase this space or insert a separator between elements. For this purpose, we have two simple elements: “Space” and “Divider”. Space may be used to increase the margin between two neighbor items and it has only one parameter - width. The Divider is a simple vertical line that has 18 pixels height by default. It also has an option to stretch it for full height of the row.
