Question

I’m trying new HTML5 tags. I want to do something like this : http://www.jsfiddle.net/TYTkZ/

I’m using this code : http://www.jsfiddle.net/cysBf/

You will see the difference when you click link. Can you help me ? Why there is space between #main and #sidebar sections?

And page hierarchy is true ?

Answer 1

Add this code in your css:

header,footer,article,section,aside,nav {
  display:block;
}

I updated your code in jsfiddle.
