title: Closing tag with ID property
body: <p><strong>Question</strong>: If I close any html tag in this fashion (Including the id property):</p>
  
  <pre><code>&lt;div id="tagid" &gt;...more html
  ...
  &lt;/div id="tagid" &gt;
  </code></pre>
  
  <p>Will it affect the page, or  won't like it, or disrupt any W3C rules...how can I put it...will it affect in any way?</p>
  
  <p><strong>Why?</strong>: Simply personal preference. <br/>
  Instead of writing additional comments next to the tag, I simply add the id to help me know WHAT tag is closed -The tag is closed any way, so I guess it won't do anything (or so I think) </p>
  
  <p>PS. FYI, I am a beginner</p>
