Font library

3 min readUpdated October 28, 2026

The Font library (Nahnu Fonts → Font library) lists every font on your site, whatever its source, with a live preview. It’s where you edit, preload, switch off or delete a font.

Preview your fonts#

At the top, Preview text sets the sample shown for every font, and the Size slider changes its size. Both are remembered in your browser.

Each font in the list#

Every row shows:

  • The font’s name, previewed in the font itself.
  • Its source: Google (with Bunny or Google), custom upload, or Adobe.
  • Its styles, with a Preloaded tag when any style is preloaded.
  • Applied to: the selectors it’s applied to, if any.
  • Its CSS variable, for example var(--nahnu-font-inter). Click to copy.
  • A switch, Use … on the site. Off keeps the font and its files but stops loading it and removes it from font pickers.
  • Edit, which opens the edit panel below the row.

Edit a font#

FieldWhat it does
Display nameThe name shown in the library. The CSS family name doesn’t change, so pages using it keep working
FallbackThe generic font used while loading or if the font fails: sans-serif, serif, monospace, cursive, system-ui or fantasy. Added to the CSS variable and “Apply to” rules
Apply to (optional)CSS selectors that use this font site-wide, separated by commas, for example body or h1, h2, h3. Leave empty to choose the font in the editor instead
StylesEvery weight and style of the font, each with Preload and Remove

Click Save to apply. The stylesheet is rebuilt and your page cache is cleared.

Preload#

Tick Preload only for the one or two styles shown at the top of your pages, like your heading font. At most 3 files are preloaded across all fonts. Adobe styles can’t be preloaded, as they’re served by Adobe. See Performance.

Remove a style#

Click Remove next to a style, then Save. Its file is deleted. Undo cancels before you save. Removing every style deletes the font, and you’re asked to confirm.

Delete a font#

In the edit panel, click Delete font and confirm. The font and its files are removed from your server. Pages that used it fall back to the fallback font.

Site output#

Below your fonts, Site output shows:

  • Stylesheet: a link to nahnu-fonts.css, or “Printed inline” if the uploads folder isn’t writable.
  • Visitor requests to Google: “None” for self-hosted fonts.
  • Any warnings from the last stylesheet build.

Regenerate CSS rebuilds the stylesheet by hand. You rarely need it: it’s rebuilt automatically whenever a font changes.

Other panels#

  • Move your fonts from Jooosi Fon appears when Jooosi Fon data is found. See Moving from Jooosi Fon.
  • Re-download your Google Fonts appears after a move, to fetch fresh copies.
