Controlling Block Order
To control the order of blocks in an XML layout update, include a “before” or “after” positioning
property in the code. To place a block—either before, or after a specific block—replace the
hyphen with the block identifier, as shown in the following examples:
before=”-” Places the block at the top of the sidebar, before other blocks.
after=”-” Places the block at the bottom of the sidebar, after other blocks.
