I added CSS support to GridFX. There are five properties that can be styled by CSS at the moment:
-fx-vertical-cell-spacing: vertical spacing between two cells (double)
-fx-horizontal-cell-spacing: horizontal spacing between two cells (double)
-fx-cell-height: height of a cell (double)

-fx-horizontal-alignment: horizontal alignment of all cells (LEFT,CENTER, or RIGHT)
