Understanding flex-direction: row in CSS
flex-direction: row is the default value for a flex container. It arranges flex items horizontally along the main axis, starting from the left and going to the right (in left-to-right languages).
Items are laid out in a horizontal row along the main axis.
The first item appears at the start (left) of the container, and subsequent items follow in order.
Main-axis properties like
justify-contentcontrol spacing between items horizontally.Cross-axis properties like
align-itemscontrol vertical alignment within the container.It is suitable for creating horizontal navigation bars, rows of cards, or any layout that flows left-to-right.
In this example, the flex container arranges .item elements in a horizontal row. They are evenly spaced along the main axis using justify-content and centered along the cross axis using align-items.
Use
flex-direction: rowfor horizontal layouts like menus, toolbars, or card rows.Combine with
justify-contentfor horizontal spacing andalign-itemsfor vertical alignment.Test the layout on different screen sizes to ensure items remain properly aligned.
Switch to
row-reverseif you need to reverse the horizontal order for RTL or design purposes.
