The flex-direction CSS property is used in flexbox layouts to determine the direction in which flex items are laid out within a flex container. It defines whether the items are displayed in a row or a column, as well as the order in which they appear. The property accepts values like row, row-reverse, column, and column-reverse.
For example, flex-direction: row; will display flex items horizontally in a row, while flex-direction: column; will stack them vertically in a column. The flex-direction property is essential for controlling the flow and arrangement of flex items within a flex container.
