.glass-btn--lg | 64px height |
.glass-btn--auto | Width: auto instead of 100% |
.glass-icon--fill | On the <svg>: deliberately filled icon (e.g. brand logos) |
Important: Buttons default to width: 100%. Use --auto for inline/auto-width buttons.
Icons: Button SVGs need no inline fill/stroke attributes – GlassKit styles them automatically: outline style (fill: none; stroke: currentColor; stroke-width: 2, round caps/joins) as the default, --secondary/--tertiary use their icon tokens, --primary renders icons filled. For deliberately filled icons (e.g. brand logos like the GitHub mark) add glass-icon--fill to the <svg>.
Links as buttons: .glass-btn also works on <a> elements – anchors render as inline-flex with text-decoration: none, so --auto shrink-wraps exactly like on a real <button>.

| Class | Description |
|---|---|
.glass-list | Grouped surface container |
.glass-list--flush | Edge-to-edge variant (no side margin / radius). Assumes parent has --gl-space-lg horizontal padding. |
.glass-list--bare | Strips background, border & shadow — for embedding inside .glass-popover or .glass-card. |
.glass-list__section-header | Section label above a .glass-list — uppercase, small, muted |
.glass-list__item | List row (use <li>, <a>, or <button>) |
.glass-list__item--interactive | Adds hover / focus / active states |
.glass-list__item--center | Centered single-text variant with ellipsis truncation |
.glass-list__item--danger | Red text for destructive actions |
.glass-list__item--accent | Primary-colored text for accent actions |
.glass-list__leading | Leading slot (28×28, holds an icon SVG) |
.glass-list__leading--lg | Large leading slot (40×40, rounded square, supports <img>) |
.glass-list__content | Flexible middle slot — takes remaining width, enables truncation |
.glass-list__title | Primary text (medium weight, ellipsis) |
.glass-list__subtitle | Secondary text (small, muted, ellipsis) |
.glass-list__subtitle--wrap | Multi-line subtitle (up to 3 lines, clamped with ellipsis) |
.glass-list__trailing | Trailing slot — chevron, value, button, badge |
.glass-list__value | Muted text inside .glass-list__trailing (e.g. file size) |
Notes:
::after. The last item never has a divider.__leading slot get an icon-aligned divider inset; items without a leading slot get a standard left/right padding inset (handled via :has()). Large leading (--lg) adjusts the divider inset automatically.24px for leading (32px for --lg), 18px for trailing, stroke: currentColor, stroke-width: 2.<ul> + <li> for semantic lists. For interactive rows wrap in <a> or <button> instead of <li> if a single-row list is needed..glass-list__section-header sits outside the .glass-list container, directly above it.--danger and --accent affect the title and leading icon color; the subtitle stays muted.Anchored dropdown / menu container. Wrap a trigger button and a .glass-popover inside a .glass-popover-anchor. Visibility is controlled via .is-open — toggling requires a tiny bit of JavaScript.

|---|---|
.glass-popover-anchor | Positioning context — wraps trigger + popover |
.glass-popover | Floating glass surface, hidden until .is-open |
.glass-popover.is-open | Visible state — fade + scale animation |
.glass-popover--top | Opens upward (above the trigger) |
.glass-popover--start | Aligns left edge with trigger |

Note: name your toggle function anything except togglePopover — that name collides with the native HTMLElement.togglePopover() method (HTML Popover API) and inline onclick handlers will throw NotSupportedError. Use a prefix like gkTogglePopover or myToggle.

Key points in this composition:
.glass-list__section-header above each list, matching iOS settings.<hr> between rows; the ::after pseudo-element handles them.--center for a "Reset to defaults" style row, gets a full-width divider above (no leading icon → standard padding inset).glass-popover--end aligns the menu to the right edge of the trigger so it doesn't overflow the viewport.glass-list--bare strips the inner glass surface so the popover stays the only glass layer.<!-- Progress -->

glass-bg as outermost container – Without the background wrapper, the aurora background is missing and glass effects won't render correctly.glass-bg--has-tab-bar – When a tab bar is present, this modifier must be set on glass-bg, otherwise the tab bar covers the bottom content.glass-btn has width: 100%. Always add glass-btn--auto for inline buttons.glass-input-group – For correct label/hint spacing.is-active → on .glass-modal-overlay (not on .glass-modal)is-active → on .glass-tab-bar__itemis-open → on .glass-accordion__itemis-open → on .glass-popover (not on the trigger or anchor)is-visible → on .glass-toastviewBox="0 0 24 24", stroke via currentColor.data-theme – Always set on <html>, never on <body> or deeper elements.<hr> or divider element between .glass-list__items. The divider is rendered via ::after and respects :has(.glass-list__leading) for the inset.togglePopover. It collides with the native HTMLElement.togglePopover() method. Use a prefix like gkTogglePopover.| Mistake | Correction |
|---|---|
is-active on .glass-modal instead of .glass-modal-overlay | Set is-active on the overlay |
glass-btn without variant (--primary etc.) | Always specify a variant |
Inputs without glass-input-group wrapper | Wrap in glass-input-group |
glass-tab-bar without glass-bg--has-tab-bar | Add modifier to the background container |
data-theme on <body> | Set on <html> |
| Progress width via class instead of inline style | Use style="width: X%" on .glass-progress__fill |
Toggle without __track > __thumb nesting | Follow correct BEM hierarchy |
Manually adding <hr> or divider element between .glass-list__items | Remove it — dividers are automatic via ::after |
Putting glass-list inside glass-popover without --bare | Add .glass-list--bare to strip the double glass surface |
JS function named togglePopover() | Rename to gkTogglePopover() or similar to avoid native API clash |
Putting .is-open on the trigger button instead of .glass-popover | The state class belongs on the popover element |
