I've currently got [this situation](http://codepen.io/anon/pen/ImEJv) - two divs where the 1st is fixed on the left and the 2nd is fluid on the right. I need to switch the HTML position of the two divs, but leave the webpage appearance unchanged. 

So,

```
<div id="fixed"></div>
<div id="fluid"></div>

```

needs to become:

```
<div id="fluid"></div>
<div id="fixed"></div>

```

But when the webpage is displayed, the fluid div needs to be on the right and the fixed on the left. I can't figure this out. Is there a way to do this?
