* @extends Ext.layout.container.Container
*
* This is a layout that enables anchoring of contained elements relative to the container's dimensions.
* If the container is resized, all anchored items are automatically rerendered according to their
- * <b><tt>{@link #anchor}</tt></b> rules.
+ * `{@link #anchor}` rules.

+ * This class is intended to be extended or created via the {@link Ext.container.AbstractContainer#layout layout}: 'anchor'
+ * config, and should generally not need to be created directly via the new keyword.
*
* AnchorLayout does not have any direct config options (other than inherited ones). By default,
* AnchorLayout will calculate anchor measurements based on the size of the container itself. However, the
- * container using the AnchorLayout can supply an anchoring-specific config property of <b>anchorSize</b>.
+ * container using the AnchorLayout can supply an anchoring-specific config property of `anchorSize`.
+ *
* If anchorSize is specifed, the layout will use it as a virtual container for the purposes of calculating
* anchor measurements based on it instead, allowing the container to be sized independently of the anchoring
* logic if necessary.
*

- * For example:
+ * @example
* Ext.create('Ext.Panel', {
* width: 500,
* height: 400,
* title: "AnchorLayout Panel",
* layout: 'anchor',
* renderTo: Ext.getBody(),
- * items: [{
- * xtype: 'panel',
- * title: '75% Width and 20% Height',
- * anchor: '75% 20%'
- * },{
- * xtype: 'panel',
- * title: 'Offset -300 Width & -200 Height',
- * anchor: '-300 -200'
- * },{
- * xtype: 'panel',
- * title: 'Mixed Offset and Percent',
- * anchor: '-250 20%'
- * }]
+ * items: [

+ * // one value specified
+ * anchor: '100%' // the width value; the height will default to auto

- * The first anchor is the percentage width that the item should take up within the container, and the
- * second is the percentage height. For example:<pre><code>
-// two values specified
-anchor: '100% 50%' // render item complete width of the container and
- // 1/2 height of the container

-// two values specified
-anchor: '-50 -100' // render item the complete width of the container
- // minus 50 pixels and

+ * // bottom offset will default to 0
*
- * <li><b>Mixed</b> : <div class="sub-desc">
- * Anchor values can also be mixed as needed. For example, to render the width offset from the container
- * right edge by 50 pixels and 75% of the container's height use:
- * <pre><code>
-anchor: '-50 75%'
