/**
- * @class Ext.layout.container.Fit
- * @extends Ext.layout.container.AbstractFit
- * <p>This is a base class for layouts that contain <b>a single item</b> that automatically expands to fill the layout's
- * container. This class is intended to be extended or created via the <tt>layout:'fit'</tt> {@link Ext.container.Container#layout}
- * config, and should generally not need to be created directly via the new keyword.</p>
- * <p>FitLayout does not have any direct config options (other than inherited ones). To fit a panel to a container
- * using FitLayout, simply set layout:'fit' on the container and add a single panel to it. If the container has
- * multiple panels, only the first one will be displayed.
- * {@img Ext.layout.container.Fit/Ext.layout.container.Fit.png Ext.layout.container.Fit container layout}
- * Example usage:</p>
- * <pre><code>
- Ext.create('Ext.panel.Panel', {
- title: 'Fit Layout',
- width: 300,
- height: 150,
- layout:'fit',
- items: {
- title: 'Inner Panel',
- html: '<p>This is the inner panel content</p>',
- bodyPadding: 20,
- border: false
- },
- renderTo: Ext.getBody()
- });
-</code></pre>
+ * This is a base class for layouts that contain **a single item** that automatically expands to fill the layout's
