<?blockmb>
Description
This command is used to add margins to the outside of a block, on the bottom side only. The margin will adjust the block’s position in relation to the text surrounding it.
* 
When a block is rotated using <?blockorient>, the content of the block only is rotated and this does not include the margins. i.e. the top margin will always be applied above the block, whether or not the block is rotated.
You may specify a priority by which this margin is judged if margins need to be merged to save space — use the <?blockmbp> command.
Syntax
<?blockmb height:uh
height
Height of the margin, with optional decimal point and optional unit of measurement
