Flexbox: a row of items

display: flex on a container lays its children out in a row. gap: 12px spaces them. flex-wrap: wrap lets them move to the next line when they run out of room; without it they shrink. flex-direction: column stacks them vertically instead.

Flexbox is the tool for one-dimensional layout: a toolbar, a row of cards, a navigation bar, a label next to a field. It replaced floats and inline-block tricks for good reason: it handles sizes and spacing for you.

.row { display: flex; gap: 12px; flex-wrap: wrap; }

Your task

Turn .row into a flex container with a 12px gap and wrapping enabled. Do not size the items.
