Spacer
A Spacer is an empty gap. Drop one between blocks when you want more breathing room than the spacing controls give you.
How to add it

Settings
The Spacer has no settings of its own. You size it with the Appearance section: set its Height (and Width if you want) to control how much space it adds. You can even give it a background colour. See Common Fields.
For small tweaks between blocks, adjust a block's Padding or Margin first. Reach for a Spacer when you want a clear, deliberate gap.
