I've searched around the forums but can't get an exact answer to the question. I want to tweak my blog layout at <http://techtites.com/> to make the content area flexible width that adjusts when the browser changes width without pushing the sidebar to the bottom.

It is currently a fixed width layout. 

Main styles that I've been playing with are:

```
#wrapper {
width:960px;
margin:0 auto;
}

#content {
padding:25px 0;
}

section {
float:left;
width:660px;
margin-right:20px;
}

aside {
float:left;
width:280px;
}

```

I want to make the *section* width to be dynamic, while retaining the *aside* to sit at the right of the window.
