title: How to make copies (and delete) a specific div using javascript?
body: <p>So I have 2 buttons (one to add a "line" and another to delete a "line"). The div that I want to operate on has a class of "line" (see code below). Basically, Every time I hit "add line" button, it should make a new "line", or another copy of that div. Same goes for Delete line button, except it deletes the one added. (There should always be at least one "line", or the original one should always be present and not be able to delete it). </p>
  
  <p>Here is what my html looks like:</p>
  
  <pre><code>    &lt;!DOCTYPE html&gt;
  &lt;!--[if IE 8]&gt;         &lt;html class="no-js lt-ie9" lang="en"&gt; &lt;![endif]--&gt;
  &lt;!--[if gt IE 8]&gt;&lt;!--&gt; &lt;html class="no-js" lang="en"&gt; &lt;!--&lt;![endif]--&gt;
  &lt;head&gt;
    &lt;meta charset="utf-8" /&gt;
    &lt;meta name="viewport" content="width=device-width" /&gt;
    &lt;title&gt; Fill out The IO &lt;/title&gt;
  
    &lt;!-- If you are using CSS version, only link these 2 files, you may add app.css to use for your overrides if you like. --&gt;
