Margins are used in anchors and within layout items.

```javascript
Rectangle {
    width: 100
    height: 100
    color: 'red'
    Rectangle {
        width: 100
        height: 50
        color: 'yellow'
        anchors.left: parent.right
        margin.left: 20
    }
}
```

```javascript
Column {
    Rectangle { color: 'red'; width: 50; height: 50; }
    Rectangle { color: 'yellow'; width: 50; height: 50; margin.top: 20; }
    Rectangle { color: 'green'; width: 50; height: 50; }
}
```
