title: difference in id selector and namespace in less
body: <p>I am trying to learn less to reduce the pain of repetitive css. One thing that confuses me is the syntax of namespace in less. To my understanding, less is compatible with css, therefore </p>
  
  <pre><code>#myelement-id{} 
  </code></pre>
  
  <p>is an id selector.  On the other hand, less supports namespace by specifying </p>
  
  <pre><code>#namespace{}
  </code></pre>
  
  <p>So, when I read a less file, how can I tell which "#" is for id selector and which is for namespace?</p>
  
  <p>Thanks for your help.</p>
