--description--

The last two challenges used the flex-direction property set to row. This property can also create a column by vertically stacking the children of a flex container.

--instructions--

Add the CSS property flex-direction to the #box-container element, and give it a value of column.

--hints--

The #box-container element should have a flex-direction property set to column.

const boxContainer = document.querySelector('#box-container');
const flexDirection = window.getComputedStyle(boxContainer)['flex-direction'];
assert.strictEqual(flexDirection, 'column');
