🙋 Introduction

The mask-size property in CSS is used to define the size of an element's mask image. Masks are used to hide or reveal parts of an element by using an image or another graphical representation.

By setting the size of the mask, you can control how the image fits the element and how it affects the visibility of the underlying content.

💡 Syntax

The syntax for the mask-size property is as follows:

Syntax
Copied
Copy To Clipboard
element {
  mask-size: value;
}

🎛️ Default Value

The default value of the mask-size property is auto, which means the mask image is displayed at its intrinsic size or scaled to fit the element, depending on the mask-repeat property.

🏠 Property Values

ValueDescription
autoThe mask image is displayed at its intrinsic size.
lengthSpecifies the width and height of the mask image using a length value (e.g., 100px, 50%).
percentageSpecifies the width and height of the mask image using a percentage of the element's size.
coverThe mask image is scaled to be as large as possible while maintaining its aspect ratio. The image will cover the entire element, and some parts may be clipped.
containThe mask image is scaled to fit within the element while maintaining its aspect ratio. The image will be fully visible, but may not cover the entire element.

📄 Example

In this example, we'll use a mask image on a div element and set the size to cover the entire element.

  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>CSS mask-size Example</title>
  <style>
    .masked-element {
      width: 300px;
      height: 300px;
      background-color: lightblue;
      mask-image: url('mask.png');
      mask-size: cover;
    }
  </style>
</head>
<body>
  <h1>Div with Mask Image and Custom Size</h1>
  <div class="masked-element"></div>
</body>
</html>

🖥️ Browser Compatibility

The mask-size property is supported in most modern browsers, including the latest versions of Chrome, Firefox, Safari, Edge, and Opera. However, it is always a good practice to test your website across different browsers to ensure compatibility.

🎉 Conclusion

The mask-size property is a versatile tool for web developers looking to create intricate designs and effects.

By controlling the size of a mask image, you can precisely determine how it interacts with the content it covers. Experimenting with different mask sizes can lead to unique and visually appealing results that enhance the user experience on your website.
