How can we use the tailwind.config.js file to implement styling that depends on whether the mode is light or dark?

We can use the theme() function and the darkMode property in the tailwind.config.js file to implement styling that depends on whether the mode is light or dark.

Here is an example of how to do this:

// tailwind.config.js

module.exports = {
  darkMode: 'class',
  theme: {
    extend: {
      colors: {
        primary: theme => ({
          light: theme('colors.blue.500'),
          dark: theme('colors.green.500'),
        }),
      },
    },
  },
};

In this example, we have set the darkMode property to 'class', which means that we will use the CSS class dark to switch between light and dark modes.

Next, we define a custom color called primary, which has different values depending on the mode. We use the theme() function to access the colors defined in Tailwind CSS, and we use the dark property to define the dark mode color.

Finally, we can use this custom color in our CSS by referencing it with the text-primary-light and text-primary-dark classes:

<!-- HTML -->

<h1 class="text-primary-light dark:text-primary-dark">Hello World!</h1>

In this example, the text color will be blue in light mode and green in dark mode.
