If the individual contained items do not have a `margins` property specified, the default margins from this property will be applied to each item.

This property may be specified as an object containing margins to apply in the format:

    {
        top: (top margin),
        right: (right margin),
        bottom: (bottom margin),
        left: (left margin)
    }

This property may also be specified as a string containing space-separated, numeric margin values. The order of the sides associated with each value matches the way CSS processes margin values:

- If there is only one value, it applies to all sides.
- If there are two values, the top and bottom borders are set to the first value and the right and left are set to the second.
- If there are three values, the top is set to the first value, the left and right are set to the second, and the bottom is set to the third.
- If there are four values, they apply to the top, right, bottom, and left, respectively.

Defaults to:

    {top:0, right:0, bottom:0, left:0}

An optional extra CSS class that will be added to the container. This can be useful for adding customized styles to the container or any of its children using standard CSS rules. See Ext.Component.ctCls also.

Note: `extraCls` defaults to `''` except for the following classes which assign a value by default:

- Absolute Layout : `'x-abs-layout-item'`
- Box Layout : `'x-box-item'`
- Column Layout : `'x-column'`

To configure the above Classes with an extra CSS class append to the default. For example, for ColumnLayout:

    extraCls: 'x-column custom-class'

Sets the padding to be applied to all child items managed by this layout.

This property must be specified as a string containing space-separated, numeric padding values. The order of the sides associated with each value matches the way CSS processes padding values:

- If there is only one value, it applies to all sides.
- If there are two values, the top and bottom borders are set to the first value and the right and left are set to the second.
- If there are three values, the top is set to the first value, the left and right are set to the second, and the bottom is set to the third.
- If there are four values, they apply to the top, right, bottom, and left, respectively.

Defaults to: `"0"`
