title: Possible to have "inheritance" in html?
body: <p>Let's say all of my html pages will have a top bar and banner with the same content. 
  Rather than copy the code for these content on all html pages, is it possible to have pages inherit the content from a base html page?</p>
  
  <p>For example : base.html can have the top bar, banner, etc (all repeated content)
  Remaining pages (index.html, about.html, etc) can inherit the content from base.html and then add more content.</p>
  
  <p>Is this possible in html or do I have to copy and paste repeating content all the time?</p>
