Creating a column layout with Nimble Builder for WordPress
Nimble Builder offers various options to create column layouts in your pages.
1 - Create columns in a section
When building in the customizer, expand a section menu and click on the column icon.
This will split your section in two columns.
You can keep adding columns up to 12 which is the limit of Nimble Builder flex grid system.
2 - Drag and drop a pre-built section with a column layout
An easier way is to use a pre-built column layout in the module picker.
On mobile devices, you can reverse the order of the columns if needed. See : https://docs.presscustomizr.com/article/343-designing-for-mobile-devices-with-wordpress-nimble-builder
