Beautiful Themes for Your Markdown
The same Markdown can read as a repository page, a research paper or a magazine article. A theme decides which — the typefaces, the scale, the spacing, the rules and the code colours — and in Mardna you can switch between them and watch the document change under you.
Five ways to typeset the same document
- GitHub
- The default, and the one to trust for a README. It follows GitHub's own Markdown rendering closely — heading scale, table rules, alert styling, code block treatment — so the preview is a fair rehearsal of the repository page. Light and dark both mirror the originals.
- Notion
- Soft and generously spaced, with restrained headings and plenty of air between blocks. It suits notes, meeting records and internal documents that people read on a screen rather than print.
- Academic
- Serif typesetting on warm paper, sized for continuous reading and for print. The natural choice for papers, reports, essays and anything destined to become a PDF.
- Minimal Mono
- One monospaced voice for headings, prose and code alike, with hairline rules and no ornament. Technical specifications, runbooks and changelogs read well in it.
- Editorial
- Magazine proportions: large headings, a strong opening, and code blocks that stay dark whatever the rest of the page is doing. Good for announcements, long-form posts and anything with a headline.
Fonts, measure and dark mode
Each theme brings its own typefaces, and the font picker overrides them independently — keep the theme's layout but set the text in Inter, in a serif face, in JetBrains Mono, or in your operating system's own interface font. Only the fonts a document actually uses are downloaded.
Every theme shares one measure, so a line of text is the same comfortable length whichever you choose and switching themes never reflows the document into something unreadable. Dark mode (⌘⇧L) is a first-class variant rather than an inverted filter: each theme defines its own dark palette, and code blocks switch to the matching dark highlighting theme.
The theme travels with the export
A theme is not a preview-only decoration. Whatever you are looking at is what gets exported: PDF prints the theme's typesetting, and HTML carries its stylesheet and fonts inside the file. Dark documents export dark.
Because switching is instant, it is worth trying two or three before you export — the same release note can read as a technical bulletin or as an announcement depending on nothing but the theme.
Frequently asked questions
Can I style Markdown with themes?
Yes. Mardna ships five themes — GitHub, Notion, Academic, Minimal Mono and Editorial — and applies them to the live preview and to every export.
Which theme should I use for a README?
GitHub. It follows GitHub’s own rendering closely, so what you see is close to what the repository page will show.
Which theme is best for a printed report or paper?
Academic — serif text on warm paper, sized for continuous reading — with Editorial as an alternative when the document wants a stronger headline.
Do themes change the exported PDF and HTML?
Yes. Exports inherit the theme, font and light or dark setting that the preview is currently using.
Is there a dark mode?
Yes, and each theme defines its own dark palette rather than inverting the light one. It follows your system setting by default and ⌘⇧L overrides it.
Can I add my own CSS?
Not inside the app today. The HTML export inlines the full stylesheet, so a custom look can be applied by editing the exported file.
