Five distinct range slider designs arranged vertically: a red square thumb, a pill shape with a hollow center, a triangular pointer, and a circular button style

Geometric Custom Range Sliders

These Geometric Custom Range Sliders push the boundaries of form styling by abandoning the standard “circle on a line” look. Created by CSS math wizard Ana Tudor, this set utilizes SCSS trigonometry to generate complex thumb shapes (like triangles and hollow pills) and CSS Mask Composition to carve out negative space. The result is a set of distinct, scalable inputs that rely on a single HTML <input> tag without any wrapper divs.

Dark UI cards with angled bottom corners and a passing light beam effect on the border, demonstrating CSS corner-shape.

Beveled Corner Glow Cards

This Beveled Corner Glow Card component demonstrates the bleeding edge of CSS UI styling. It primarily utilizes the new corner-shape property to create chamfered (angled) edges without complex clip-paths, while implementing a sophisticated CSS Mask fallback for older engines. The interaction features a “scanning” light beam effect on the border, powered by CSS Houdini for buttery smooth interpolation.

An image framed by a decorative, wavy border created with pure CSS masks and gradients.

Images Inside Wiggly Boxes

A decorative image frame created entirely with CSS mask compositing. It combines radial-gradient layers with conic-gradient and the intersect composite operator to sculpt a scalloped, wavy border, while the CSS round() function ensures perfect pattern alignment along the edges.

See the Pen Images Inside Wiggly Boxes.

A full-screen image slider where images transition with a diagonal wipe effect as the user scrolls.

Scroll-Triggered Image Stack with Gradient Mask Reveal

As the user scrolls down, images transition not by simple sliding or fading, but through a complex diagonal “wiping” animation controlled by dynamic gradients, all while the text content remains fixed over the changing background.

Wavy Image Gallery

Images appear as jigsaw puzzle pieces with interlocking edges that can visually fit together.

Wall of Text: Blogged

Wall of Text: Blogged

A futuristic, interactive blog card featuring AI-generated content fetched dynamically via JavaScript. The layout utilizes advanced CSS techniques like :has() for expandable sections, masking and blend modes for rich graphical elements, and variable-driven cursor tracking animations, creating a dynamic and engaging reading experience.

Single Element Progress

Elegant, segmented radial charts that smoothly fill upon page load, showcasing the capabilities of modern CSS without JavaScript.

Fancy Corner Decoration for Images

Fancy Corner Decoration for Images

A border effect for an <img> tag - the size of the decorative edge, created with repeating-conic-gradient and -webkit-mask, is dynamically calculated via a complex calc() function controlled by CSS variables.

Dissolving Image Edges

Dissolving Image Edges

Creating a “grainy” edge effect for a circular image using SVG filters. The effect is achieved through a complex combination of feGaussianBlur and feTurbulence primitives with multiple feComposite operations to control the alpha channel.

See the Pen Dissolving Image Edges.

GSAP Sprite Mask Animation

GSAP Sprite Mask Animation

The demo uses GSAP to programmatically control the CSS mask property and applies the ease: steps() function for precise, frame-by-frame switching between 20 sprite mask states, creating a drawing or layered revelation effect.

Pure CSS Loader #11/2020 - Ripples

Pure CSS Loader #11/2020 - Ripples

Spectacular animated ring loader built on the advanced capabilities of CSS Houdini to define and smoothly transition custom properties, enabling complex and dynamically changing geometry via conic and radial gradients.

Smooth Corners with CSS

Smooth Corners with CSS

A progressive technique for creating complex UI shapes using the CSS Houdini Paint API - a squircle is generated by the smooth-corners worklet, surpassing the capabilities of border-radius. The shape’s curvature is dynamically controlled via the --smooth-corners CSS Custom Property, while the effect itself is built with a combination of pseudo-elements, mask, and clip-path.

See the Pen Smooth Corners with CSS.

A Gallery of Squiggle Images

CSS Grid creates a 3‑column base, then each image is individually shifted with translate to break the alignment — resulting in a scattered, organic layout. The wave‑shaped border is drawn using mask with repeating radial gradients; the design is purely visual and static.

Scroll Mask Indicators

A modern and clean way to indicate scrollability: the “fade-to-mist” effect is implemented using mask-image and linear-gradient, while key parameters of the fade phase are precisely tuned using @property.

See the Pen Scroll Mask Indicators.

Avatar Indicators Using CSS Mask and Trigonometry

Avatar status indicators positioned with CSS masks and trigonometry (cos, sin). Custom properties --status-angle, --status-size, --status-offset control the dot’s position along the circumference; a radial‑gradient mask cuts a hole for the indicator to peek through. JavaScript only tweaks the variables — the logic itself is pure CSS.

CSS Bookmark

A state-driven animation, controlled via the “checkbox hack,” showcases the power of CSS @property (Houdini) for smoothly animating gradients and mask properties. A complex multi-layered bookmark shape is created with an SVG mask, while the entire activation effect choreography is built on synchronized @keyframes.

See the Pen CSS Bookmark.
