jQuery class within class selector

<div class="outer">
     <div class="inner"></div>
</div>

how do I find the inner div here?

$container.find('.outer .inner')

is just going to look for a div with class="outer inner", is that correct?

so I tried

$container.find('.outer > .inner')

but that doesn't seem to be working.

Edit:

I know its easy to find with something like

$container.find('.outer').find('.inner')

but I'm looking for the kind of single selector syntax which reads better imho.
