title: Can <header> replace <head> in HTML?
body: <p>I just started reading about headers and I found an article here on SO dating to 2011 which says that the <code>&lt;header&gt;</code> tag is another way of writing <code>&lt;div class="header"&gt;</code>. </p>
  
  <p>However, just for fun, I experimented with it and replaced <code>&lt;head&gt;</code> with <code>&lt;header&gt;</code> and found no change in my site at all. Even the <code>&lt;title&gt;</code> displays correctly. </p>
  
  <p>Hence my question. Is the <code>&lt;header&gt;</code> tag in html5 a replacement for the <code>&lt;head&gt;</code> tag?
  If not, could anyone offer a suggestion on why things haven't changed on my site?</p>
  
  <p>Thanks in advance.</p>
