Default and 1 additional Tailwind theme

Question

I have been asked to add 1 new theme to an existing project that currently uses Tailwind.

The new theme should only take affect when 'theme-name' exists in the body tag class attribute.

The existing tailwind.config.js is like this:

const defaultTheme = require('tailwindcss/defaultTheme');

var colors = {
  gray: {
    DEFAULT: '#868692',
    50: '#F9FAFB',
    100: '#F5F5FA',
    200: '#E9E9EE',

  },
  primary: {

        // TODO: Install Gibson font
        mono: [
          'canada-type-gibson, sans-serif',
          ...defaultTheme.fontFamily.mono
        ]
        // serif: ['icomoon, sans-serif', ...defaultTheme.fontFamily.serif]
      },
      zIndex: {
        dropdown: 1000,

      transitionProperty: {

      },
      transitionTimingFunction: {
        'out-back': 'cubic-bezier(0.34, 1.56, 0.64, 1)'
      }
    }
  },
  plugins: [require('@tailwindcss/forms'), require('@tailwindcss/typography')]
};

...only the colours are changing in this new additional theme.

Could anyone please point me in the right direction to set this up? I already have the 'theme-name' in my body tag class attribute.

Thanks for any guidance, K...

You could consider using `[.theme-name_&]:` [arbitrary variant](https://tailwindcss.com/docs/hover-focus-and-other-states#using-arbitrary-variants) to apply different colors where needed, i.e. `bg-black [.theme-name_&]:bg-white`. You could also refactor [the variant into a Tailwind plugin](https://tailwindcss.com/docs/plugins#static-variants). — Wongjn, Jun 01 '23 at 16:17

            transitionTimingFunction: {

            }
          }
        }
      ]
    })
  ]
};

or you might just try [tw-colors](https://github.com/L-Blondy/tw-colors), it is way easier and cleaner — L.Blondy, Jun 13 '23 at 08:29
