Flexbox is a one-dimensional CSS layout that can control the way items are spaced out and aligned within a container.
To use it, give an element a display property of flex. This will make the element a <em>flex container</em>. Any direct children of a flex container are called <em>flex items</em>.
Create a .gallery selector and make it a flex container.
You should have a .gallery selector.
assert.exists(new __helpers.CSSHelp(document).getStyle('.gallery'));
Your .gallery selector should have a display property set to flex as the value.
assert.equal(new __helpers.CSSHelp(document).getStyle('.gallery')?.display, 'flex');
