Tailwind CSS Theming - Flowbite

Use the theming options from the configuration file to override the default utility classes from FlowBite

You can use the theme object from the configuration file to define any style related classes, such as the color palette, fonts, breakpoints, and more.

// tailwind.config.js
const colors = require('tailwindcss/colors')

module.exports = {
  theme: {
    screens: {
      sm: '480px',
      md: '768px',
      lg: '976px',
      xl: '1440px',
    },
    colors: {
      gray: colors.coolGray,
      blue: colors.lightBlue,
      red: colors.rose,
      pink: colors.fuchsia,
    },
    fontFamily: {
      sans: ['Graphik', 'sans-serif'],
      serif: ['Merriweather', 'serif'],
    },
    extend: {
      spacing: {
        '128': '32rem',
        '144': '36rem',
      },
      borderRadius: {
        '4xl': '2rem',
      }
    }
  }
}

Theme structure

Some of the more widely used theme keys are screens, colors, and spacing as one of the core utility classes.

You can read all of the configurable keys on Tailwind CSS.

Breakpoints

Use the screens key to update the responsive breakpoints.

// tailwind.config.js
module.exports = {
  theme: {
    screens: {
      'sm': '640px',
      'md': '768px',
      'lg': '1024px',
      'xl': '1280px',
      '2xl': '1536px',
    }
  }
}

Colors

Use the colors key to set the colors of your site.

// tailwind.config.js
module.exports = {
  theme: {
    colors: {
      transparent: 'transparent',
      black: '#000',
      white: '#fff',
      gray: {
        100: '#f7fafc',
        // ...
        900: '#1a202c',
      },

      // ...
    }
  }
}

Spacing

Update the spacing key to set new values for the spacing utilities (such as paddings and margins).

// tailwind.config.js
module.exports = {
  theme: {
    spacing: {
      px: '1px',
      0: '0',
      0.5: '0.125rem',
      1: '0.25rem',
      1.5: '0.375rem',
      2: '0.5rem',
      2.5: '0.625rem',
      3: '0.75rem',
      3.5: '0.875rem',
      4: '1rem',
      5: '1.25rem',
      6: '1.5rem',
      7: '1.75rem',
      8: '2rem',
      9: '2.25rem',
      10: '2.5rem',
      11: '2.75rem',
      12: '3rem',
      14: '3.5rem',
      16: '4rem',
      20: '5rem',
      24: '6rem',
      28: '7rem',
      32: '8rem',
      36: '9rem',
      40: '10rem',
      44: '11rem',
      48: '12rem',
      52: '13rem',
      56: '14rem',
      60: '15rem',
      64: '16rem',
      72: '18rem',
      80: '20rem',
      96: '24rem',
    },
  }
}

Customizing the theme

By default, the configuration file will set the base utility classes from FlowBite and Tailwind CSS. However, you can customize them by using the extend object.

Extending

Use the extend object if you want to keep the values from the default settings but you want to extend them with your own.

For example, you can keep all of the default breakpoints, but you may want to add another larger one for the screens key.

// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      // Adds a new breakpoint in addition to the default breakpoints
      screens: {
        '3xl': '1600px',
      }
    }
  }
}

Overriding

Alternatively, you can also completely override certain settings.

For example, the following code will override all of the opacity settings with your own.

// tailwind.config.js
module.exports = {
  theme: {
    // Replaces all of the default `opacity` values
    opacity: {
      '0': '0',
      '20': '0.2',
      '40': '0.4',
      '60': '0.6',
      '80': '0.8',
      '100': '1',
    }
  }
}
