What is the difference between justify-content and align-items?

justify-content aligns items along the Main Axis (horizontal by default), while align-items controls alignment along the Cross Axis (vertical by default). If you change flex-direction to column, their roles geometrically swap.

Is the gap property supported in all browsers?

Yes, the gap property is fully supported across all modern browsers for Flexbox. It has become the industry standard for creating gutters between items, eliminating the need for complex margin workarounds.

Why do my flex items overflow the container?

Flex items overflow because the flex container defaults to flex-wrap: nowrap, forcing all items onto a single line regardless of width. Adding flex-wrap: wrap to the parent container resolves this by allowing items to drop to the next line.
