# Icon

Icon renders a named glyph from Mosaic's icon set. It sizes through the `size` variant and inherits color from `currentColor`. Any glyph can be swapped per name through `appearance.icons` on `MosaicProvider`. Mosaic's styling applies to an override just like the built-in glyph — so swapped icons stay visually consistent — and the override also receives `data-cl-slot="icon"` for targeting.
Icon renders a named glyph from Mosaic's icon set. It sizes through the `size` variant and inherits color from `currentColor`. Any glyph can be swapped per name through `appearance.icons` on `MosaicProvider`. Mosaic's styling applies to an override just like the built-in glyph — so swapped icons stay visually consistent — and the override also carries the `.cl-icon` class and `data-size` attribute for targeting.

Set `placement` when the icon sits beside text inside a container. It adds no styling of its own; it reflects `data-icon="inline-start"` or `data-icon="inline-end"` so the container can react — a `Button`, for example, tightens its padding on the side the icon sits with `:has([data-icon='inline-end'])`. The values are the CSS logical directions, so they follow the writing mode rather than naming a physical edge. Leave it unset for a standalone icon.

### Overriding a glyph

Pass `appearance.icons` to `MosaicProvider` to replace a glyph by name. The override is a function receiving the resolved props — Mosaic's sizing/color `className` and `data-cl-slot` — which you spread onto your own element. Because Mosaic's styling applies to the override too, the replacement only supplies its `viewBox` and paths.
Pass `appearance.icons` to `MosaicProvider` to replace a glyph by name. The override is a plain element; Mosaic clones it with the resolved sizing `className` and `data-size`, keeping any class the element already had. The replacement only supplies its `viewBox` and paths.

Mosaic's styling applies to an override just like the built-in glyph — so swapped icons stay visually consistent — and the override also carries the `.cl-icon` class and `data-size` attribute for targeting.

Set `placement` when the icon sits beside text inside a container. It adds no styling of its own; it reflects `data-icon="inline-start"` or `data-icon="inline-end"` so the container can react — a `Button`, for example, tightens its padding on the side the icon sits with `:has([data-icon='inline-end'])`. The values are the CSS logical directions, so they follow the writing mode rather than naming a physical edge. Leave it unset for a standalone icon.

# Icon

Icon renders a named glyph from Mosaic's icon set. It sizes through the `size` variant and inherits color from `currentColor`. Any glyph can be swapped per name through `appearance.icons` on `MosaicProvider`. Mosaic's styling applies to an override just like the built-in glyph — so swapped icons stay visually consistent — and the override also receives `data-cl-slot="icon"` for targeting.
Icon renders a named glyph from Mosaic's icon set. It sizes through the `size` variant and inherits color from `currentColor`. Any glyph can be swapped per name through `appearance.icons` on `MosaicProvider`. Mosaic's styling applies to an override just like the built-in glyph — so swapped icons stay visually consistent — and the override also carries the `.cl-icon` class and `data-size` attribute for targeting.

Set `placement` when the icon sits beside text inside a container. It adds no styling of its own; it reflects `data-icon="inline-start"` or `data-icon="inline-end"` so the container can react — a `Button`, for example, tightens its padding on the side the icon sits with `:has([data-icon='inline-end'])`. The values are the CSS logical directions, so they follow the writing mode rather than naming a physical edge. Leave it unset for a standalone icon.

### Overriding a glyph

Pass `appearance.icons` to `MosaicProvider` to replace a glyph by name. The override is a function receiving the resolved props — Mosaic's sizing/color `className` and `data-cl-slot` — which you spread onto your own element. Because Mosaic's styling applies to the override too, the replacement only supplies its `viewBox` and paths.
Pass `appearance.icons` to `MosaicProvider` to replace a glyph by name. The override is a plain element; Mosaic clones it with the resolved sizing `className` and `data-size`, keeping any class the element already had. The replacement only supplies its `viewBox` and paths.
