# `canvas`

```strand
element canvas: node
```

Draws with code: `canvas { draw: (c) => … }`.

It takes no children.

Also every prop and event of [`node`](/reference/elements/node.html.md).

| Prop | Type | |
| --- | --- | --- |
| `draw` | `fn(Canvas)` | Draws on the canvas. It runs again when what it reads changes, not every frame, so `t`, `wave(…)` and `noise` of `t` are refused in it (`check::time_in_canvas`): animate the canvas's own props (`rotate: t * 90deg`) or draw every frame with a `shader`. |
