CSS animations have been rudimentary despite keyframes and scroll-driven events, resembling 1960s cartoons.The article explores adding an extra dimension to animations using masking in CSS.Masking in CSS controls visibility using a bitmap, vector, or gradient mask image, hiding content behind the mask.Clip-path and mask are used for defining visible areas in animations, with clip paths creating hard-edged clipping areas.The complexity of paths in clip-path may affect performance, leading to the use of CSS masks which have baseline properties.Masks can use bitmap, vector, or gradient mask images to control visibility, allowing for versatile creative possibilities.The mask property in CSS includes values for mask-clip, mask-mode, mask-origin, mask-position, mask-repeat, mask-size, and mask-type.CSS masks can be applied using bitmap formats, vector graphics, or conical, linear, and radial gradients.The article demonstrates practical examples of using clip-path and mask-image in CSS animations to enhance storytelling and engagement.Masking adds depth and engagement to web animations, making them more compelling while maintaining lightweight efficiency.
