mask-*-[customValue]

For enhanced customization, users can incorporate dynamic values directly within HTML classes for any mask-* property. By adopting the syntax mask-*-[customValue], users can seamlessly integrate personalized values into various mask properties like image, size, repeat, position, clip, type, origin, mode, and composite. This approach empowers users to effortlessly fine-tune the appearance of their elements by providing custom values specific to each mask property directly in their HTML markup.

<div class="mask-image-[url('/path/to/mask.svg')]">
  <!-- Your content here -->
</div>

Customization

Customize the default values or add your own variations for each property in the theme section of your Tailwind CSS configuration file: For custom values, it's essential to encapsulate them within a mask: {} object. Within this object, you can define specific properties such as size, repeat, position, clip, type, origin, mode, and composite. This structure ensures clarity and allows you to tailor each property according to your preferences.

// tailwind.config.js
module.exports = {
  // ... other configurations
  theme: {
    mask: {
      image: {
        // Customize image options
      },
      size: {
        // Customize size options
      },
      // ... other customization options
    },
  },
};

Certainly! Here are the examples using your Tailwind CSS mask plugin classes:

<figure class="bg-blue-500 rounded-lg overflow-hidden">
    <img src="/yourImagePath" alt="" class="h-96 from-black to-transparent to-90% mask-image-gradient-to-b" />
</figure>
