# Sandbox.UI.CanvasPanel.Content

```csharp
Panel Content { get; set; }
```

Ordinary panels placed in canvas coordinates. Their CSS transforms, layout, focus and input
work normally. The content has a stable 1000 x 1000 layout size (set its Style to change it),
with visible overflow so panels can also be placed at negative or larger coordinates.
Pan/zoom transform the whole subtree without changing its layout. Created only when used.

Declared in [Sandbox.UI.CanvasPanel](/api/Sandbox.UI.CanvasPanel).
Assembly: `Sandbox.Engine`.
