You may have noticed that your images have all moved onto the same row.
The `flex-wrap` property determines how your items should behave when the flex container is too small. Setting this property to `wrap` will allow your items to wrap to the next row/column (depending on your main axis), where `nowrap` will prevent your items from wrapping. When this is set to `nowrap`, items may either shrink to fit or overflow.
Give the `#gallery` selector a `flex-wrap` property set to `wrap`. You should see your images take a four-column layout. This is because you set their `width` to `25%` in an earlier step.

Your `#gallery` selector should have a `flex-wrap` property set to `wrap`.
