    To customize the opacity values for all opacity-related utilities at once, use the opacity section of your tailwind.config.js theme configuration:

    If you want to customize only the background opacity utilities, use the backgroundOpacity section:

    1.   // tailwind.config.js
    3.     theme: {
    4.       extend: {
    5.         backgroundOpacity: {
    6. +         '10': '0.1',
    7. +         '20': '0.2',
    8. +         '95': '0.95',
    9.       }
    10.     }
    11.   }

    You can control which variants are generated for the background opacity utilities by modifying the property in the variants section of your tailwind.config.js file.

    Disabling

    If you don’t plan to use the background opacity utilities in your project, you can disable them entirely by setting the backgroundOpacity property to false in the corePlugins section of your config file:

    1.   // tailwind.config.js
    2.   module.exports = {
    3.     corePlugins: {
    4.       // ...
    5. +     backgroundOpacity: false,
    6.   }
