+</span> * A specialized container representing the viewable application area (the browser viewport).
+ *
+ * The Viewport renders itself to the document body, and automatically sizes itself to the size of
* the browser viewport and manages window resizing. There may only be one Viewport created
- * in a page. Inner layouts are available by virtue of the fact that all {@link Ext.Panel Panel}s
+ * in a page.
+ *
+ * Like any {@link Ext.container.Container Container}, a Viewport will only perform sizing and positioning
+ * on its child Components if you configure it with a {@link #layout}.
+ *
+ * A Common layout used with Viewports is {@link Ext.layout.container.Border border layout}, but if the
+ * required layout is simpler, a different layout should be chosen.
+ *
+ * For example, to simply make a single child item occupy all available space, use
+ * {@link Ext.layout.container.Fit fit layout}.
+ *
+ * To display one "active" item at full size from a choice of several child items, use
+ * {@link Ext.layout.container.Card card layout}.
+ *
+ * Inner layouts are available by virtue of the fact that all {@link Ext.panel.Panel Panel}s
* added to the Viewport, either through its {@link #items}, or through the items, or the {@link #add}
- * method of any of its child Panels may themselves have a layout.</p>
- * <p>The Viewport does not provide scrolling, so child Panels within the Viewport should provide
- * for scrolling if needed using the {@link #autoScroll} config.</p>
- * <p>An example showing a classic application border layout:</p><pre><code>
-new Ext.Viewport({
- layout: 'border',
- items: [{
- region: 'north',
- html: '<h1 class="x-panel-header">Page Title</h1>',
- autoHeight: true,
- border: false,
- margins: '0 0 5 0'
- }, {
- region: 'west',
- collapsible: true,
- title: 'Navigation',
- width: 200
- // the west region might typically utilize a {@link Ext.tree.TreePanel TreePanel} or a Panel with {@link Ext.layout.AccordionLayout Accordion layout}
- }, {
- region: 'south',
- title: 'Title for Panel',
- collapsible: true,
- html: 'Information goes here',
- split: true,
- height: 100,
- minHeight: 100
- }, {
- region: 'east',
- title: 'Title for the Grid Panel',
- collapsible: true,
- split: true,
- width: 200,
- xtype: 'grid',
- // remaining grid configuration not shown ...
- // notice that the GridPanel is added directly as the region
- // it is not "overnested" inside another Panel
- }, {
- region: 'center',
- xtype: 'tabpanel', // TabPanel itself has no title
- items: {
- title: 'Default Tab',
- html: 'The first tab\'s content. Others may be added dynamically'
- }
- }]
-});
-</code></pre>
- * @constructor
- * Create a new Viewport
- * @param {Object} config The config object
- * @xtype viewport
+ * method of any of its child Panels may themselves have a layout.
+ *
+ * The Viewport does not provide scrolling, so child Panels within the Viewport should provide

+ * collapsible: true,
+ * title: 'Navigation',
