Sorry , guess i wasnt clear:
I am talking about the sequence of html5 code , not the css .
I would expect the html order(sequence) to be :
<aside class="left-sidebar">
<div class="middle">
<aside class="right-sidebar">
but it isnt, its :
<div class="middle">
<aside class="left-sidebar">
<aside class="right-sidebar">
Can someone explain why ?
I just added some <h3> code to hightlight the Outline: then handed it to : https://gsnedders.html5.org/outliner/
to Outline it for me ,
Which shows :
<div class="middle">
<aside class="left-sidebar">
<aside class="right-sidebar">
But magically , the browser displays :
<aside class="left-sidebar">
<div class="middle">
<aside class="right-sidebar">

You can position elements with CSS wherever you want. The (html) source order of your elements does not has to be the same order visually. In your case the CSS float, left and margin properties positioned the main content and sidebars where you see them on the screen.
It's usually a good thing to have the main content div at the top in the source, because you want to make sure that search engine bots will scan it properly.
almostbob 866 Retired: passive income ROCKS
gentlemedia has the key
the sidebars are less important than the main content,
this code layout ensures::
that bots index the content in the desired order, and
display it in the desired layout
on a slow cell data plan, the important content displays before unimportant sidebars even download
== on-page optimising
please put all css in the external css file, shrink page size download css once

First oops I see is use of a div as a major section container. Try section element instead. Save div for really odd-ball stuff.

I've been hearing lately that you want to inline (into the HTML head) a small amount of CSS used to render the above-the-fold content, for faster perceived performance. Slower connections don't have to download a huge external file with a lot of CSS properties for stuff not being used at the moment.
