--description--

The tweet embed header and footer used the flex-direction property earlier with a row value. Similarly, the items inside the .profile-name element would work well stacked as a column.

--instructions--

Add the CSS property flex-direction to the header's .profile-name element and set the value to column.

--hints--

Your .follow-btn should be rendered on the page. Be sure to turn off any extensions such as ad blockers.

const followButton = document.querySelector('.follow-btn');
const displayStyle = window.getComputedStyle(followButton)['display'];
assert.isNotNull(followButton);
assert.notStrictEqual(displayStyle, 'none');

The .profile-name element should have a flex-direction property set to column.

const profileName = document.querySelector('.profile-name');
const flexDirection = window.getComputedStyle(profileName)['flex-direction'];
assert.strictEqual(flexDirection, 'column');
