This section uses alternating challenge styles to show how to use CSS to position elements in a flexible way. First, a challenge will explain theory, then a practical challenge using a simple tweet component will apply the flexbox concept.

Placing the CSS property display: flex; on an element allows you to use other flex properties to build a responsive page.

--instructions--

Add the CSS property display to #box-container and set its value to flex.

--hints--

#box-container should have the display property set to a value of flex.

assert($('#box-container').css('display') == 'flex');
