<h2>Showing a Node</h2>
<p>By default, Node instances are hidden using the node's <code>hidden</code> attribute and the CSS <code>display</code>. Calling the <code>show</code> method displays the node.</p>
<pre class="code prettyprint">Y.one('#demo').show();</pre>
<h2>Hiding a Node</h2>
<p>The opposite of <code>show</code>, the <code>hide</code> method sets the node's <code>hidden</code> attribute to <code>true</code> and the CSS <code>display</code> to <code>none</code>.</p>
<pre class="code prettyprint">Y.one('#demo').hide();</pre>
<h2>Toggling visibility</h2>
<p>You can toggle the visibility between show and hide using <code>toggleView</code>.</p>
<pre class="code prettyprint">Y.one('#demo').toggleView();</pre>
<h2>Checking visibility</h2>
<p>You can detect whether a node is visible or not by checking for the hidden attribute:</p>
<pre class="code prettyprint">var isHidden = Y.one('#demo').getAttribute('hidden') === 'true';</pre>
