Theme mode

Fower comes with built-in support for managing theme mode. We call it theme mode, not color mode.

Why we call it theme mode? Because it's not just about color, you will learn more about it by reading the bellow docs.

Basic

Now, Let's build a dark mode UI. How to write dark mode style? It's very simple, just add the --dark postfix to the Atomic props like bgGray800--dark, white--dark. The live demo:

// import { useMode } from '@fower/react' function App() { const { mode, setMode } = useMode() function toggleMode() { setMode(mode === 'dark' ? 'light' : 'dark') } return ( <Box h-300 roundedLG bgGray800--dark bgOrange100 p4 toCenter> <Box column toCenter spaceY3 gray800 white--dark textCenter> <Box as="button" onClick={toggleMode} p3 cursorPointer outlineNone roundedFull orange200 bgBlack black--dark bgOrange200--dark > Toggle {mode} </Box> <Box as="h1">Hello, I am the Title</Box> <Box as="h2">I am the Subtitle</Box> </Box> </Box> ) }

// import { useMode } from '@fower/react'

function App() {
  const { mode, setMode } = useMode()
  function toggleMode() {
    setMode(mode === 'dark' ? 'light' : 'dark')
  }
  return (
    <Box h-300 roundedLG bgGray800--dark bgOrange100 p4 toCenter>
      <Box column toCenter spaceY3 gray800 white--dark textCenter>
        <Box
          as="button"
          onClick={toggleMode}
          p3
          cursorPointer
          outlineNone
          roundedFull
          orange200
          bgBlack
          black--dark
          bgOrange200--dark
        >
          Toggle {mode}
        </Box>
        <Box as="h1">Hello, I am the Title</Box>
        <Box as="h2">I am the Subtitle</Box>
      </Box>
    </Box>
  )
}

How to toggle theme mode? It's also very simple, just remove or add a .dark CSS class to the HTML root element, You can see the live demo above.

Config mode

By default, dark mode is built-in support in Fower, you can use --dark postfix with Atomic Props directly. You can customize theme mode by config theme 'modes' option:

import { setConfig } from '@fower/core'

setConfig({
  mode: {
    currentMode: 'light',
    modeList: [
      'red', // red mode
      'blue', // red mode
      'large', // large text mode
    ],
    classPrefix: '',
  },
})

Then you can you --red, --blue, --large postfix with Atomic Props:
