Why does justify-content change directions when I use column?

justify-content aligns items based strictly on the Main Axis. When flex-direction changes to column, the Main Axis rotates 90 degrees to become vertical, which means justify-content now controls vertical spacing instead of horizontal spacing.

Does row-reverse change the DOM order?

No, row-reverse only alters the visual CSS painting order on the screen. The underlying HTML document and the DOM tree remain exactly the same, ensuring screen readers and keyboard navigation still follow the original top-to-bottom HTML structure.

When should I use column-reverse?

column-reverse is essential for mobile-responsive design inversions. For example, if a desktop layout has text on the left and an image on the right (row), using column-reverse on mobile devices instantly stacks the image below the text without modifying the HTML structure.
