Styling

Style components with className utilities or typed props. Text.js apps have no stylesheets.

#Utilities

className takes Tailwind-style utilities. One unit is one cell.

<Box className="flex-row gap-2 p-1 border rounded">  <Box className="flex-col grow border rounded px-1 bg-surface">    <Text bold>p-1 · gap-2</Text>    <Text color="muted">1 unit = 1 cell</Text>  </Box>  <Box className="flex-col grow border rounded px-1 border-accent">    <Text color="accent">border-accent</Text>  </Box></Box>

#Typed props

Every utility has a prop. Props win over className.

<Box flexDirection="column" padding={1} border="rounded" borderColor="accent">  <Text bold>Typed props</Text></Box>

#Colors

Use hex, Tailwind names or theme tokens like fg, muted, surface, accent, success and danger. Tokens follow the active theme.

#Themes

Five presets ship built in: geistDark, geistLight, opencodeDark, tokyoNight and amberCrt.

<ThemeProvider theme="amberCrt">  <Box className="border rounded p-1">    <Text color="accent">amberCrt</Text>  </Box></ThemeProvider>

const brand = createTheme({ id: "brand", name: "Brand", accent: "#ffffff" }, "geistDark");

#Responsive viewports

Apps fill the docked DevTools console by default (viewport.responsive), and resize as you drag the panel. Lay out with flex and read the size when you need it:

const { cols } = useViewport();const sidebar = cols >= 90;

The page can only see a docked panel. Undocked DevTools, DevTools zoom and the Console sidebar are invisible to it, so the app uses viewport.width × viewport.height (default 120×36) or a size you pin:

text.resize(120, 36)   // pin a sizetext.responsive(true)  // fit the console again
