Office UI Fabric offers a grid layout mechanism documented here. Column entries in a row (of class "ms-Grid-row") are of class "ms-Grid-col".
I cannot get the vertical alignment of a column entry to work properly, as all entries are always rendered with top alignment. From what I understand, the css property "align-items: center;" should do the trick, but it doesn't impact vertical alignment.
Is it possible to override vertical alignment to have all entries in a grid center-aligned ?
