alignment

Aligned Centered.

Aligned Right.

This attribute specifies the horizontal or vertical positioning of a tile within its cluster. If a tile is within a column, the possible values are:

left, right or centered. (default: left)

If a tile is within a row, the possible values are:

top, bottom or centered. (default: centered)

You cannot specify the alignment along the long axis of a cluster. The first and last tiles in the cluster always align themselves to the ends of the column or row.
