The bevel is an inset shadow stack: the light caught in the glass thickness, a bright bevel on the lit top-left, a softer counter-bevel, a shaded inner reflex, a faint chromatic fringe and a highlight cast by the fixed light. The specular ring is a masked hairline lit from the top left, with a glint where that light sits. Custom properties resolve on the declaring element, so surfaces and buttons feed both their own tokens. ============================================ */ .lg-glass-surface, .lg-button { --lg-rim-gain: calc( var(--lg-rim-tangent-alpha, 1) * var(--lg-debug-tangent-scale, 1) * var(--lg-rim-micro-mask, 1) * var(--lg-debug-micro-scale, 1) * var(--lg-rim-corner-mask, 1) * var(--lg-debug-corner-scale, 1) * var(--lg-debug-rim-alpha-scale, 1) ); --lg-glass-rim: inset 0 0 calc(12px * var(--lg-rim-scale)) calc(-4px * var(--lg-rim-scale)) rgb(255 255 255 / calc(var(--lg-glow-alpha) * var(--lg-rim-gain))), inset calc(1.5px * var(--lg-rim-scale)) calc(2.5px * var(--lg-rim-scale)) calc(1px * var(--lg-rim-scale)) -2px rgb(255 255 255 / calc(var(--lg-rim-light) * 0.7)), inset calc(-1.5px * var(--lg-rim-scale)) calc(-2px * var(--lg-rim-scale)) calc(1px * var(--lg-rim-scale)) -2px rgb(255 255 255 / calc(var(--lg-rim-light) * 0.55)), inset -0.3px -1px 4px 0 rgb(0 0 0 / calc(var(--lg-rim-dark) * 0.1)), inset -1.5px 2.5px 0 -2px rgb(0 0 0 / calc(var(--lg-rim-dark) * 0.14)), inset 0 3px 4px -2px rgb(0 0 0 / calc(var(--lg-rim-dark) * 0.14)), inset var(--lg-rim-ca-offset) 0 3px -1px rgb(80 160 255 / var(--lg-rim-ca-alpha)), inset calc(-1 * var(--lg-rim-ca-offset)) 0 3px -1px rgb(255 90 150 / var(--lg-rim-ca-alpha)), inset var(--lg-rim-offset-x) var(--lg-rim-offset-y) 3px rgb(255 255 255 / var(--lg-rim-alpha)); /* to bottom right keeps both highlights on the corners at any aspect ratio; a fixed angle would smear them along a wide pill. */ --lg-specular-ring: radial-gradient( circle at calc(var(--lg-light-x) * 100%) calc(var(--lg-light-y) * 100%), rgb(255 255 255 / calc(var(--lg-light-level) * 0.85)), transparent 42% ), linear-gradient( to bottom right, rgb(255 255 255 / calc(var(--lg-specular-peak) * var(--lg-rim-gain))) 0%, rgb(255 255 255 / calc(var(--lg-specular-floor) * var(--lg-rim-gain))) 32%, rgb(255 255 255 / calc(var(--lg-specular-floor) * var(--lg-rim-gain))) 68%, rgb(255 255 255 / calc(var(--lg-specular-counter) * var(--lg-rim-gain))) 100% ); } /* Glass Surface - Global Refraction */ .lg-glass-surface { --lg-thickness: calc(1 + var(--lg-light-strength) * 0.35); --lg-surface-blur-base: calc(var(--lg-glass-blur) * var(--lg-thickness)); --lg-surface-blur: var(--lg-surface-blur-base); --lg-surface-alpha: var(--lg-glass-alpha); --lg-surface-lift: 0; --lg-light-strength: calc(var(--lg-light-level) * 0.45); /* Bevel thickness (scaled by distance-aware factor) */ --lg-rim-scale: calc(var(--lg-rim-width-scale, 1) * var(--lg-debug-rim-thickness, 1)); --lg-rim-offset-max: 4.5px; --lg-rim-offset-max-scaled: calc(var(--lg-rim-offset-max) * var(--lg-rim-scale)); --lg-rim-tangent-alpha: 1; --lg-rim-micro-mask: 1; --lg-rim-corner-mask: 1; --lg-rim-ca-offset: calc(2px * var(--lg-debug-ca-offset-scale, 1)); --lg-rim-ca-alpha: calc(0.06 * var(--lg-debug-ca-scale, 1)); --lg-rim-offset-x: clamp( calc(-1 * var(--lg-rim-offset-max-scaled)), calc( var(--lg-light-dir-x) * -1 * var(--lg-rim-offset-max-scaled) * (0.6 + var(--lg-light-strength)) ), var(--lg-rim-offset-max-scaled) ); --lg-rim-offset-y: clamp( calc(-1 * var(--lg-rim-offset-max-scaled)), calc( var(--lg-light-dir-y) * -1 * var(--lg-rim-offset-max-scaled) * (0.6 + var(--lg-light-strength)) ), var(--lg-rim-offset-max-scaled) ); --lg-rim-light: calc(var(--lg-reflex-light) * var(--lg-rim-gain)); --lg-rim-dark: var(--lg-reflex-dark); --lg-rim-alpha: calc( (0.05 + var(--lg-light-strength) * 0.12 + var(--lg-fresnel, 0) * 0.35 + var(--lg-specular) * 0.32) * var(--lg-rim-gain) ); position: relative; border-radius: var(--lg-panel-radius, var(--lg-radius-lg)); isolation: isolate; background: transparent; color: var(--lg-foreground); transition: box-shadow var(--lg-motion-duration) ease, transform var(--lg-motion-duration) ease; box-shadow: var(--lg-panel-elevation-shadow, var(--lg-shadow)); overflow: hidden; contain: layout paint style; } .lg-glass-surface[data-lg-preset='subtle'] { --lg-surface-blur: min(var(--lg-surface-blur-base), 8px); --lg-surface-alpha: max(var(--lg-glass-alpha), 0.06); --lg-rim-offset-max: 1.5px; } .lg-glass-surface[data-lg-preset='standard'] { --lg-surface-blur: min(var(--lg-surface-blur-base), 14px); --lg-surface-alpha: max(var(--lg-glass-alpha), 0.08); } .lg-glass-surface[data-lg-preset='prominent'] { --lg-surface-blur: min(var(--lg-surface-blur-base), 18px); --lg-surface-alpha: max(var(--lg-glass-alpha), 0.12); } .lg-glass-surface[data-lg-preset='control'] { --lg-surface-blur: min(var(--lg-surface-blur-base), 10px); --lg-surface-alpha: max(var(--lg-glass-alpha), 0.08); --lg-rim-offset-max: 1.25px; } .lg-glass-surface[data-lg-preset='showcase'] { --lg-surface-blur: min(var(--lg-surface-blur-base), 24px); } /* An interactive surface brightens a touch on hover, wherever the pointer rests on it. */ .lg-glass-surface[data-lg-interactive='true']:hover { --lg-surface-lift: 0.04; } /* The lift eases in and out.
