 This value signals that a block supports some of the CSS style properties related to spacing. When it does, the block editor will show UI controls for the user to set their values, if [the theme declares support](/docs/how-to-guides/themes/theme-support.md#cover-block-padding).

 When the block declares support for a specific spacing property, the attributes definition is extended to include the `style` attribute.

-A spacing property may define an array of allowable sides that can be configured. When arbitrary sides are defined only UI controls for those sides are displayed. Axial sides are defined with the `vertical` and `horizontal` terms, and display a single UI control for each axial pair (for example, `vertical` controls both the top and bottom sides). A spacing property may support arbitrary individual sides **or** axial sides, but not a mix of both.
