Use the Add Column element to quickly add a [Layout Column](/app-editor/page-editor/built-in-elements/layout-column.md) element to a [Layout Row](/app-editor/page-editor/built-in-elements/layout-row.md).
The Layout Column is already preset with:
* 100% width at the main setting and overridden to *Default* for the desktop screen size.
* Margin at the bottom by using the [Custom CSS Classes](/app-editor/page-editor/page-element-settings.md#custom-css-classes) setting. For more information on adjusting the spacing see [Padding and Margin](/app-editor/page-editor/padding-and-margin.md).
