How to add new attributes

module.exports = {
  content: [
    './app/**/*.{js,ts,jsx,tsx}',
    './lib/**/*.{js,ts,jsx,tsx}',
  ],
  theme: {
    extend: {
      backgroundImage: {
        'gradient-radial': 'radial-gradient(var(--tw-gradient-stops))',
        'gradient-conic':
          'conic-gradient(from 180deg at 50% 50%, var(--tw-gradient-stops))',
      },
      blur: {
        xs: "0.03em",
      },
    },
  },
  plugins: [],
}

!important

The important option lets you control whether or not Tailwind’s utilities should be marked with !important. This can be really useful when using Tailwind with existing CSS that has high specificity selectors.

/** @type {import('tailwindcss').Config} */
module.exports = {
  important: true,
}
