# `Plushie.Widget.Responsive`
[🔗](https://github.com/plushie-ui/plushie-elixir/blob/v0.7.2/lib/plushie/widget/responsive.ex#L1)

Responsive layout, adapts to available size by reporting resize events.

The renderer wraps child content in a sensor that sends
`%WidgetEvent{type: :resize}` events so the Elixir app can adjust
its view based on the measured size.

## Props

| Name | Type | Default | Description |
|------|------|---------|-------------|
| `width` | `:fill \| :shrink \| {:fill_portion, pos_integer()} \| number()` | `nil` | Container width. Default: fill. |
| `height` | `:fill \| :shrink \| {:fill_portion, pos_integer()} \| number()` | `nil` | Container height. Default: fill. |
| `event_rate` | `integer()` | `nil` | Max events per second for coalescable events. |
| `a11y` | `%Plushie.Type.A11y{} \| map() \| keyword()` | `nil` | Accessibility annotations. |

```

Accessibility annotations.

Accepts `%Plushie.Type.A11y{} | map() | keyword()`.

# `build`

@spec build(widget :: t()) :: Plushie.Widget.ui_node()
```

Converts this widget struct to a `ui_node()` map. Validates at most one child.

```elixir
@spec event_rate(widget :: t(), value :: integer() | nil) :: t()
```

Max events per second for coalescable events.

Accepts `integer()`.

# `extend`

```elixir
@spec extend(widget :: t(), children :: [Plushie.Widget.child()]) :: t()
```

Appends multiple children to the widget.

# `height`

# `responsive`

directly in view functions:

    import Plushie.Widget.Responsive, only: [responsive: 2]

    responsive("my-id", prop: value)

# `width`

```elixir

  value :: (:fill | :shrink | {:fill_portion, pos_integer()} | number()) | nil
) ::
  t()
```

Container width. Default: fill.

# `with_options`

```elixir
