The plain-English version
A layout system that arranges items along a main axis and a cross axis.
Why it matters
It suits rows or columns whose items need alignment, wrapping, or flexible space distribution.
Let’s make it click
A toolbar lets search grow while keeping a Filter button at its natural width.
Vibe Bro’s heads-up
Flex items can have minimum sizes that prevent expected shrinking; inspect overflow rather than forcing fixed widths.

Supported: One-dimensional alignment and the warning about shrinking below content minimums agree with MDN; the toolbar is an illustrative design.
