What is Image Masking in CSS?

Image masking in CSS is a technique that enables you to apply a mask to an element’s content, revealing only a portion of it while hiding the rest. It’s a powerful way to create visually striking effects and emphasize specific parts of an image.

CSS Properties for Image Masking

To implement image masking, you can use the following CSS properties:
