Theme

Theme

A project that changes nothing gets a look Staleless designed: readable typography, a working sidebar, dark mode, strong contrast, and semantic HTML.

Everything below is optional.

Presets

Four, and each is a starting point rather than a lock:

Preset	For	Character
Standard	Most products	Sidebar, comfortable measure, soft corners.
Minimal	Small, literate docs	Less furniture, more text.
Developer	API and tooling docs	Denser, code forward.
Help centre	Support content	Cards and categories first.

Fonts

Three pairings, each with a sans and a mono face:

Pairing	Character
Geist	The default. Neutral and modern.
Humanist	Warmer, for prose-heavy documentation.
System	The reader’s own system fonts. Nothing to download.

Code themes

Five: default, plain, classic, vivid, contrast.

contrast exists for accessibility. Choose it when your readers include people who need more separation than a designer would pick.

The fields you set

accentcolour

Your brand colour. It drives links, buttons and active states. Leave it unset to use the Staleless accent.

logoasset

Shown in the header. Upload it in the asset library.

faviconasset

The browser-tab icon. This is the one themable field with no default: unset means your site ships no icon rather than the Staleless mark. Our identity does not belong on your documentation’s tab.

social imageasset

The card image when somebody links to your site. Unset means no card.

code themestring

One of the five above.

Contrast is checked, not hoped for

An accent colour that fails contrast against the background in either light or dark mode is reported when you set it. Inline formatting cannot produce an inaccessible combination.

Custom CSS

A scoped stylesheet of your own, on Pro and above. It is scoped rather than global so a rule cannot break the sidebar, the search dialog or the accessibility of a control.

Arbitrary JavaScript is not accepted.

Light and dark

Both, always, plus a system setting that follows the reader. There is no dark-mode flash: the theme is resolved before the first paint.

Note

“Powered by Staleless” appears in the footer on Free. Pro and above remove it. See Plans.
