| position: relative; |
| width: 100px; |
| height: 100px; |

| .flex { |
| display: flex; |
| flex-wrap: wrap; |

| .grid { |
| display: grid; |
| grid-template-columns: 200px; |

| .item { |
| flex: none; |

| <p> |
| For a flex or grid container, if an axis has a scrollable overflow value, |
| content distribution in that axis uses unsafe default overflow alignment. |
| This does not affect behavior, as the initial value for these cases is unsafe. |
