FlexBox: FlexBox: an overview, Justify Content.

Updated November 3, 2026

1. FlexBox: an overview (Apprentice): Setting display to flex on an element lines up its children side by side in a row, and flex-direction can turn that row into a column.
2. Justify Content (Apprentice): The justify-content property on a flex container decides where the extra space goes, so its items can sit at the start, the end, the center or spread out.
