Flexbox (Flexible Box Layout) revolutionized CSS by providing a one-dimensional layout system designed specifically for distributing space and aligning content.

How it works: When you set display: flex on an element, it becomes a flex container. Its direct children automatically become flex items that flow along a main axis (horizontal by default). This single property transforms stacked block elements into a horizontal row.

The two axes:
• Main axis – The primary direction items flow (row = left→right)
• Cross axis – Perpendicular to main (row = top→bottom)
