How is "flex-grow: 1" working on .row and .row hasn't been defined as a flex box?
At least, I don't see where .row is being defined as a flex box.

As Eric pointed out, flex items are child elements of flexboxes. If you look in "flexbox.css" on line 6 you will see where "
display: flex" is set on the body element, which is the parent of of the .row's.
