| border: black solid 3px; |

| /* |
| In this testcase, div#child-block's vertical (top and bottom) |
| margins should collapse with div#parent-block-container's vertical |
| (top and bottom) margins because div#child-block has no used |
| padding-top and no used padding-bottom. On the other hand, |
| div#parent-block-container's vertical (top and bottom) margins |
| should NOT collapse with div#grand-parent-block-container's vertical |
| (top and bottom) margins because div#parent-block-container, after |
| resolving percentage values, has an used padding-top value and an used |
| padding-bottom value. |
