## Anatomy

The LCD’s span with a different light. It stays the same in every finish, as a display does.

## Variants

- Frequency
- Level
- A word

## States

- Small
- Default
- Large

## Props and options

| Name | Kind | Description |
| - | - | - |
| data-ghost | attribute | The unlit segments, the same width as the value. |

## Usage notes

The glass stays dark in every finish: it is lit, not painted.

## Accessibility

- It is text: the value and the unit are read; the ghost is not.
- Light on glass is above 12:1; the glow is decoration on top of that.
