A non-full Aside shares its vertical space with the section it belongs to. If the aside callout is taller than the section text, extra whitespace appears below the main content to fill the gap. Only add aside callouts to sections with enough body text to match the aside height.Callout is supported, but this site intentionally prefers the semantic variants whenever possible.
