60+ CSS mask Examples

A pure CSS typography effect that simulates a realistic, perspective-cast drop shadow. The main text is styled with a metallic linear gradient using background-clip: text. The shadow is generated via a ::before pseudo-element that duplicates the text content using attr(data-text). This shadow layer is then skewed, scaled down, blurred, and faded out using a linear gradient mask-image to mimic natural light diffusion.

An elegant pure-CSS implementation of the classic Kanizsa Square optical illusion. Requiring zero HTML, the layout combines layered conic and radial gradients inside a single pseudo-element to render four black ‘Pacman’ circles. This arrangement triggers a Gestalt perception where the brain automatically draws subjective white boundary contours to construct a floating foreground square.

Interactive CSS Tear Strip Animation simulates the satisfying physical action of tearing open a cardboard package. It cleverly uses an invisible <input type="range"> linked to the CSS Scroll-Driven Animations API (animation-timeline: --thumb). As the user drags the slider, CSS variables dynamically update clip-path, box-shadow, and transform properties to reveal the content beneath while curling the torn strip. A JavaScript fallback ensures compatibility for browsers without native scroll-timeline support.

Pure CSS Trigonometric Flight Range Slider uses CSS math functions like sin() and clamp() to dynamically scale a custom airplane thumb and cast realistic altitude shadows based on the input’s current percentage. It features a responsive container query that swaps the plane for a helicopter on narrow screens, and includes dedicated high-contrast mode styles for robust accessibility.

Rollback Ball 3D Toggle Switch is a highly tactile, skeuomorphic switch concept. When clicked, a textured 3D ball realistically rolls across the track, cast-shadows shifting in unison. An ES6 JavaScript class dynamically reads the CSS animation duration, disables the input during the roll, and automatically resets the toggle state once the animation completes. A stellar example of interactive micro-design.

Single Div Vintage TV CSS Illustration is a masterclass in CSS gradient art. Using only one div and its ::before/::after pseudo-elements, it renders a retro television set. The body, screen, antenna, and speaker grill are meticulously drawn using layered linear-gradient, radial-gradient, and repeating-linear-gradient. The mask-image property is cleverly used to carve out the control knobs. A brilliant example of pushing CSS drawing to its limits.

3D Zig-Zag Edge CSS Dividers creates a paper-cut illusion using only CSS. It relies on conic-gradient applied to both the background (for shading) and -webkit-mask (for the jagged shape). CSS variables control the size and depth of the teeth. This approach requires zero extra DOM elements or SVG files, making it a highly optimized solution for section transitions.

3D Star Wars Lightsaber Theme Toggle relies on trigonometric CSS functions sin() and cos() to rotate vector elements along a 3D spherical path as the toggle slides. Custom numeric transitions are facilitated by redefining modern @property rules inside a @layer properties block, animating the --progress variable dynamically across state-driven keyframes. While providing a deeply thematic visual experience, performing continuous trigonometric transformations and animating complex CSS masks can trigger layout rasterization strain on standard devices, requiring GPU acceleration layers to preserve smooth 3D motion.

Slice Action List Item achieves a physical text-splitting illusion by duplicating each text node into two overlapping, masked <span> blocks aligned via absolute positioning and CSS pseudo-elements. A jQuery handler triggers a sequential timeline: an SVG checkmark collapses, a dynamically generated absolute .line animates across the list item simulating a laser slice, and then both text halves rotate outward in opposite directions. The implementation provides a distinct, highly engaging micro-interaction, although triggering jQuery .animate() alongside CSS transforms can lead to inconsistent frame timing if layout changes overlap with GPU-accelerated compositing layers. (Requires: jquery.js)
