title: bootstrap label "for" attribute use?
body: <p>I know how to use label.
  I know that the <code>For</code> attribute should have Id of the input.
  Also I know there is another way to link the label to an input by wrapping it around the input like this:</p>
  
  <pre><code>&lt;label&gt;test &lt;input type="text" /&gt;&lt;/label&gt;
  </code></pre>
  
  <p>What I couldn't figure out is why in bootstrap,there is no Id  for the textarea and the label tag is assigned to word "name" as follow: </p>
  
  <pre><code>&lt;label for="name" &gt; test &lt;/label&gt;
  &lt;textarea class=form-control" rows="3" &gt;&lt;/textarea &gt;
  </code></pre>
