So the first tag is a simple one that any one who has done any type of web coding is probably familiar with.

“<!–…–>” is used to open a comment that can be seen in the source code and is not shown in the browser to the web viewer.  Any thing placed between the “<!–” and a closing tag of “–>” can be used by developers to write just about anything they’d like.  I have used the comment tag to help me divide up a web page and easily see where different parts or sections begin and end.  As far as I can tell, there is no difference in the use of this tag in HTML5 as in previous versions.  Below is an example of how the comment code could be used:

<div id="footer">

     <div id="copyright">

          <span>Copyright &#169; 2011 - <a href="http://dexterousdesigns.com">DexterousDesigns.com</a> - All rights reserved. </span>

     </div> <!-- End of Copyright -->

</div> <!-- End of Footer -->

While this may seem pointless in the above code, it can come in quite handy when you have several small sections of code opening within another section. Placing comments along side the closing of a section within another section will help you to remember what just what particular section is being closed.
