The breakout mark sets block nodes to extend wider than the normal content area. When no breakout mark is present, elements fit within the narrower margins dictated by ADF’s normal layout. Confluence uses a fairly narrow, portrait layout inspired by modern websites like medium.com. For some content, particularly technical content like code blocks, this can be too restrictive for comfortable viewing. A breakout mark sets wider margins for specific block node types where this is anticipated to be a concern.

Jira effectively renders everything as full-width at all times, so the mark currently would not make sense on Jira and there is no reason to expect this to change in the immediate future.↩︎
The width attribute takes precedence over mode, but the mode attribute is still required due to backward-compatibility restrictions on the ADF structure.↩︎
