Columns and Inner Columns Overview

/Editor FOUNDATIONS

"Formerly Flexbox."

This is what reads in between the parenthesis when you hover over an inner column from the Widget Panel. But what does this mean?

Without getting too far into the technical jargon, Flexbox is the
CSS layout module that powers columns and inner columns in Editor 2.0. It’s the technology that helps you align widgets and other layout elements. Flexbox is particularly useful for creating complex layouts that adapt seamlessly and are responsive to various screen sizes.
