+ * @class Roo.Element
+ * Represents an Element in the DOM.<br><br>
+ * Usage:<br>
+<pre><code>
+var el = Roo.get("my-div");
+
+// or with getEl
+var el = getEl("my-div");
+
+// or with a DOM element
+var el = Roo.get(myDivElement);
+</code></pre>
+ * Using Roo.get() or getEl() instead of calling the constructor directly ensures you get the same object
+ * each call instead of constructing a new one.<br><br>
+ * <b>Animations</b><br />
+ * Many of the functions for manipulating an element have an optional "animate" parameter. The animate parameter
+ * should either be a boolean (true) or an object literal with animation options. The animation options are:
+<pre>
+Option Default Description
+--------- -------- ---------------------------------------------
+duration .35 The duration of the animation in seconds
+easing easeOut The YUI easing method
+callback none A function to execute when the anim completes
+scope this The scope (this) of the callback function
+</pre>
+* Also, the Anim object being used for the animation will be set on your options object as "anim", which allows you to stop or
+* manipulate the animation. Here's an example:
+<pre><code>
+var el = Roo.get("my-div");
+
+// no animation
+el.setWidth(100);
+
+// default animation
+el.setWidth(100, true);
+
+// animation with some options set
+el.setWidth(100, {
+ duration: 1,
+ callback: this.foo,
+ scope: this
+});
+
+// using the "anim" property to get the Anim object
+var opt = {
+ duration: 1,
+ callback: this.foo,
+ scope: this
+};
+el.setWidth(100, opt);
+...
+if(opt.anim.isAnimated()){
+ opt.anim.stop();
+}
+</code></pre>
+* <b> Composite (Collections of) Elements</b><br />
+ * For working with collections of Elements, see <a href="Roo.CompositeElement.html">Roo.CompositeElement</a>
+ * @constructor Create a new Element directly.
+ * @param {String/HTMLElement} element

+ * Aligns this element with another element relative to the specified anchor points. If the other element is the

+ * The position parameter is optional, and can be specified in any one of the following formats:
+ * <ul>
+ * <li><b>Blank</b>: Defaults to aligning the element's top-left corner to the target's bottom-left corner ("tl-bl").</li>
+ * <li><b>One anchor (deprecated)</b>: The passed anchor position is used as the target element's anchor point.
+ * The element being aligned will position its top-left corner (tl) to that point. <i>This method has been
+ * deprecated in favor of the newer two anchor syntax below</i>.</li>
+ * <li><b>Two anchors</b>: If two values from the table below are passed separated by a dash, the first value is used as the
+ * element's anchor point, and the second value is used as the target's anchor point.</li>
+ * </ul>
+ * In addition to the anchor points, the position parameter also supports the "?" character. If "?" is passed at the end of
+ * the position string, the element will attempt to align as specified, but the position will be adjusted to constrain to
+ * the viewport if necessary. Note that the element being aligned might be swapped to align to a different position than
+ * that specified in order to enforce the viewport constraints.
+ * Following are all of the supported anchor positions:

+ Value Description

+ tl The top left corner (default)
+ t The center of the top edge
+ tr The top right corner
+ l The center of the left edge
+ c In the center of the element
+ r The center of the right edge
+ bl The bottom left corner
+ b The center of the bottom edge
+ br The bottom right corner
+ </pre>
+ Example Usage:
+ <pre><code>
+ // align el to other-el using the default positioning ("tl-bl", non-constrained)
+ el.alignTo("other-el");
+
+ // align the top left corner of el with the top right corner of other-el (constrained to viewport)

+/**
+ * @class Roo.Fx
+ * <p>A class to provide basic animation and visual effects support. <b>Note:</b> This class is automatically applied
+ * to the {@link Roo.Element} interface when included, so all effects calls should be performed via Element.
+ * Conversely, since the effects are not actually defined in Element, Roo.Fx <b>must</b> be included in order for the
+ * Element effects to work.</p><br/>
+ *
+ * <p>It is important to note that although the Fx methods and many non-Fx Element methods support "method chaining" in that
+ * they return the Element object itself as the method return value, it is not always possible to mix the two in a single
+ * method chain. The Fx methods use an internal effects queue so that each effect can be properly timed and sequenced.
+ * Non-Fx methods, on the other hand, have no such internal queueing and will always execute immediately. For this reason,
+ * while it may be possible to mix certain Fx and non-Fx method calls in a single chain, it may not always provide the
+ * expected results and should be done with care.</p><br/>
+ *
+ * <p>Motion effects support 8-way anchoring, meaning that you can choose one of 8 different anchor points on the Element
+ * that will serve as either the start or end point of the animation. Following are all of the supported anchor positions:</p>
+<pre>
+Value Description
+----- -----------------------------
+tl The top left corner
+t The center of the top edge
+tr The top right corner
+l The center of the left edge
+r The center of the right edge
+bl The bottom left corner
+b The center of the bottom edge
+br The bottom right corner
+</pre>
+ * <b>Although some Fx methods accept specific custom config parameters, the ones shown in the Config Options section
+ * below are common options that can be passed to any Fx method.</b>
+ * @cfg {Function} callback A function called when the effect is finished
+ * @cfg {Object} scope The scope of the effect function
+ * @cfg {String} easing A valid Easing value for the effect
+ * @cfg {String} afterCls A css class to apply after the effect
+ * @cfg {Number} duration The length of time (in seconds) that the effect should last
+ * @cfg {Boolean} remove Whether the Element should be removed from the DOM and destroyed after the effect finishes
+ * @cfg {Boolean} useDisplay Whether to use the <i>display</i> CSS property instead of <i>visibility</i> when hiding Elements (only applies to
+ * effects that end with the element being visually hidden, ignored otherwise)
+ * @cfg {String/Object/Function} afterStyle A style specification string, e.g. "width:100px", or an object in the form {width:"100px"}, or
+ * a function which returns such a specification that will be applied to the Element after the effect finishes
+ * @cfg {Boolean} block Whether the effect should block other effects from queueing while it runs
+ * @cfg {Boolean} concurrent Whether to allow subsequently-queued effects to run at the same time as the current effect, or to ensure that they run in sequence
+ * @cfg {Boolean} stopFx Whether subsequent effects should be stopped and removed after the current effect finishes
