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.
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.
