-The shorthand you often see in tutorials is `flex: 1` or `flex: 2` and so on. This is the same as writing `flex: 1 1 0` or `flex: 2 1 0` and so on, respectively. The items get minimum size due to `flex-basis: 0` and then proportionally grow to fill the available space. In this case, the `flex-shrink` value of `1` is redundant because the item starts with minimum size.
