title: CSS Selector <tag name>#<ID> Patterns -- Any Siginifance?
body: <p>When working on a web project with a 'not so good' codebase, I often see in JS/CSS selectors written like</p>
  
  <pre><code>div#myID
  </code></pre>
  
  <p>This seems wrong....</p>
  
  <p><a href="http://jsfiddle.net/bobber205/yeJRQ/" rel="nofollow">http://jsfiddle.net/bobber205/yeJRQ/</a></p>
  
  <p>Example above. This means, if for some reason, you change the tag the id belongs to, you have, possible, LOTS of css to change....</p>
  
  <p>What's up with people doing that? Is it faster? Is the speed improvement worth it? So curious. :P</p>
