title: jQuery + How can I select only the first instance of each element?
body: <p>take the following html for example:</p>
  
  <pre><code>&lt;h1&gt;Level 1 Header&lt;/h1&gt;
  &lt;h1&gt;My Second Level 1 Header&lt;/h1&gt;
  &lt;h1&gt;And a third for kicks&lt;/h1&gt;
  
  &lt;h2&gt;Level 2 Header&lt;/h2&gt;
  &lt;h2&gt;2nd Level 2 Header&lt;/h2&gt;
  
  &lt;p&gt;Here is a paragraph.&lt;/p&gt;
  &lt;p&gt;Here is a paragraph number 2.&lt;/p&gt;
  &lt;p&gt;And paragraph number 3.&lt;/p&gt;
  
  &lt;ul&gt;
  &lt;li&gt;list item 1&lt;li&gt;
  &lt;li&gt;list item 2&lt;li&gt;
  &lt;li&gt;list item 3&lt;li&gt;
  &lt;li&gt;list item 4&lt;li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>How can I select only the first instance of each element?</p>
  
  <p>I'm looking to hide all, in exception to "first" of each element.</p>
  
  <p>Thanks in advance!</p>
