    </div>

    @if($loop->last) </div> @endif
@endforeach

`$loop` property	Description
`$loop->index`	0-based current index
`$loop->iteration`	1-based current iteration
`$loop->first`	`true` on first iteration
`$loop->last`	`true` on last iteration
`$loop->count`	Total items in the array
`$loop->remaining`	Items remaining
`$loop->even`	`true` if even-numbered iteration
`$loop->odd`	`true` if odd-numbered iteration
