About this block

Prose With Margin Notes is an annotated essay. Each body paragraph carries a superscript marker that pairs with a numbered note in a narrow side column, so a methodology aside or an honest caveat sits beside the sentence it qualifies without breaking the reading line. A heading and lede open the section above the annotated rows.

Each row is an object with a lead clause, the rest of the paragraph, and its margin note, and the superscript number is derived from the array index so the two stay in sync. Three rows is the natural length. Write the notes as the caveat a careful reader would otherwise email you about, the sample size that was smaller, the cohort that predates the data, not a second helping of the claim.

When to use

Reach for this block when the argument is strong and the caveats are real, a research writeup, a data story, a methodology note where the footnotes are the credibility. The margin keeps the qualifiers visible without derailing the main line, which reads as confidence rather than hedging. Use prose-two-column when the essay flows without asides, this block when the asides matter.

What you can display

One strong use is the honest version of a research finding. Other essays:

• Methodology note. How a study was actually run, with the sample caveats kept in the margin where they belong.
• Data story. A surprising result told in prose, each claim annotated with the cohort it came from.
• Founding argument. A point of view whose supporting detail reads as asides rather than interruptions.

Tip: write the note before the claim, if the caveat is not worth a margin the sentence probably does not need annotating.
