Where are my other .inner elements?

Where are my other .inner elements?

I am brand new to this...just learning this weekend.

I have this section in my html:
<div class="inner" id="hello">Hello</div>
<div class="inner" id="goodbye">Goodbye</div>
<div class="inner" id="aloha">Aloha</div>

When I run this jquery: 
$('.inner')

...I only get back the first element with id='hello'

Shouldn't I get all three?

Thanks
