css - Is there a way in Bootstrap to "split" a column on small screens?

Question

I'm using Bootstrap 3. On large screens I want to have a sidebar on the left and the maincontent on the right. On small screens I want to have important blocks of the sidebar on top, then the maincontent, then the less important blocks of the sidebar. Is there a way to achieve that?

Here's a JS Bin showing the problem: http://jsbin.com/wibucopi/1/ and below is the current code (which, however, displays all sidebar content on top on small screens).

<div class="container-fluid">
  <div class="row">
    <div class="col-sm-3">
      <div class="upper" style="background:red">
        <h3>I want to be <b>above</b> the main content on small screens!</h3>
      </div>
      <div class="lower" style="background:green">
        <h3>I want to be <b>below</b> the main content on small screens!</h3>
      </div>
    </div>
    <div class="col-sm-9">
      <h1>Main content</h1>
      <p>Lorem ipsum dolor sit amet</p>
    </div>
  </div>
</div>

I've already played around with col-sm-pull/push-x, but I could only achieve that the whole sidebar is displayed below the maincontent on small screens.

I don't want to duplicate content and show / hide it with visible-XY, hidden-XY, as the page would get bigger and it feels just wrong.

It would be great to have a pure Bootstrap css solution, or at least a css only one (I wouldn't like to use js).

You could do something like this:

Bootply Demo

HTML:

<div class="container-fluid">
  <div class="row">
    <div class="upper col-sm-3" style="background:red">
      <h3>I want to be <b>above</b> the main content on small screens!</h3>
    </div>
    <div class="col-sm-9 col-sm-pull-right">
      <h1>Main content</h1>
      <p>Lorem ipsum dolor sit amet</p>
      <p>Lorem ipsum dolor sit amet</p>
      <p>Lorem ipsum dolor sit amet</p>
      <p>Lorem ipsum dolor sit amet</p>
      <p>Lorem ipsum dolor sit amet</p>
    </div>    
    <div class="lower col-sm-3" style="background:green">
      <h3>I want to be <b>below</b> the main content on small screens!</h3>
    </div>
  </div>
</div>

CSS:

@media (min-width: 768px) {
  .col-sm-pull-right {
      float: right;
  }
}
.lower {
  clear: left;
}
