# Class Ext.ux.layout.CenterLayout

Package: | Ext.ux.layout
Defined In: | CenterLayout.js
Class: | CenterLayout
Extends: | FitLayout

This is a very simple layout style used to center contents within a container. This layout works within nested containers and can also be used as expected as a Viewport layout to center the page layout.

As a subclass of FitLayout, CenterLayout expects to have a single child panel of the container that uses the layout. The layout does not require any config options, although the child panel contained within the layout must provide a fixed or percentage width. The child panel's height will fit to the container by default, but you can specify `autoHeight:true` to allow it to autosize based on its content height. Example usage:

    // The content panel is centered in the container
    var p = new Ext.Panel({
        title: 'Center Layout',
        layout: 'ux.center',
        items: [{
            title: 'Centered Content',
            width: '75%',
            html: 'Some content'
        }]
    });

    // If you leave the title blank and specify no border
    // you'll create a non-visual, structural panel just
    // for centering the contents in the main container.
    var p = new Ext.Panel({
        layout: 'ux.center',
        border: false,
        items: [{
            title: 'Centered Content',
            width: 300,
            autoHeight: true,
            html: 'Some content'
        }]
    });

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'
