title: Frameset Alternative HTML5 to change certain div content
body: <p>I couple of years ago I paid a simple HTML pages with a side bar and a 'main frame'. The Main Frame would auto refresh into another page using: <strong><em>meta http-equiv="refresh" content="5; URL='/target.html'"</em></strong> </p>
  
  <p>Now I want to update it to HTML5. I still want the sidebar to stay 24/7 in place and the main frame content to refresh or change into another page/content (being it videos, paragraphs of text or images). </p>
  
  <p>I found out that framesets don't work anymore. Cause I had it set up to: Sidebar = a frame and Main Frame = a frame and just refresh the source of the main frame into the next page of content. </p>
  
  <p>Any alternatives?</p>
