Margins

A :margins node puts transparent margins around its child allowing the current frame to show through.

{
    :type :margins
    :cols 0 # number, optional
    :rows 0 # number, optional
    :border :rounded # border type, dynamic, optional
    :border-fg nil # color, dynamic, optional
    :border-bg nil # color, dynamic, optional
    :node {} # a node
}

:cols and :rows

These properties set the size of the node inside of the :margins node; they do not refer to the width of the margins. A value of 0 for either property means that the node will use the full space available to it in that dimension.

:border

The border style for the borders around the node.

:border-fg and :border-bg

The foreground and background color of the border.

:node

A valid layout node.

Dynamic

All dynamic properties are invoked with the same arguments:

1. The current value of :node.
