|
|
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.
