Obsidian Cornell Notes Template: Callouts Plus One CSS Snippet

The Cornell layout — a narrow cue column, a wide notes area, a summary band across the bottom — is the part of the method most note apps cannot reproduce. This Obsidian Cornell notes template builds it from three plain callouts and a single CSS snippet. No community plugins, no special syntax to learn: the notes stay ordinary Markdown that would still read fine anywhere else.

What's inside the Cornell notes template for Obsidian

• Templates/ — Cornell Note for any material, and Class Notes (Cornell), a variant that adds course, professor and date frontmatter so class notes stay sortable by subject.
• Notes/ — three fully worked examples: Statistics - Describing Data, History - The Printing Press and Biology - Photosynthesis Overview. Open one in reading view first; the layout explains itself faster than any description.
• cornell.css — the layout engine, shipped pre-enabled in the vault's snippets folder. It floats the [!cue] callout left at 32% width, sets [!notes] beside it and clears [!summary] underneath — the classic Cornell page, collapsing to stacked blocks on narrow windows.

Cornell notes in Obsidian without plugins

Everything runs on what Obsidian ships with, so you can keep restricted mode on when opening the vault — there is nothing to whitelist. The three zones are just callouts, and the snippet can be toggled in Settings → Appearance → CSS snippets if you ever want the plain stacked view back. Because the structure is Markdown plus CSS rather than a plugin, there is nothing here for an Obsidian update to break.

How the Cornell note-taking workflow runs

1. During class — write only in the notes zone. Short lines, abbreviations, gaps are fine.
2. Same day — fill the cue column: turn each chunk of notes into a question or keyword you could be asked on an exam.
3. Then the summary — two or three sentences in your own words, written without looking back at the notes.
4. To review — cover the notes column and answer the cue questions out loud. The cues make self-testing possible; the summary tells future-you what the page was about.

The three example notes show every stage filled in, including the kind of cue questions worth writing.
