jquery themeroller how do I change the style of my div

Hi, I am new to theme roller and am having trouble getting started.  I downloaded the sample and just want to create a div with a background color and rounded corners.  There is an example of an accordion with nice looking divs, but it looks like they just give it an id of accordion, and the rest is done magically.  I can't really see how to get started.

you need to read the documentation of each of the components you are interested in. For example, if you are interested in the accordion, the API is at:

You will see a "View Source" link that shows you how that particular example was implemented.

Thanks, but I am not looking for information on the accordion.

Let me try to clarify.

I want to be able to style my divs in the same manner as those in the accordion, without the actual accordion functionality.  I can't follow the example, because the only thing I can see in the example is that a particular div is has an id of accordion.  I am looking for a way to figure out how to style my form with a downloaded themeroller theme.
did you download the theme ?
If yes go to ..jquery-ui-1.8.custom\development-bundle\themes\base and you will see

Add this to your page...and add classes to your div:

<div class="ui-widget ui-widget-content ui-corner-all">
This is Test <br />

From Jquery site:
Note: ThemeRoller uses CSS3 border-radius for corner rounding, which is not currently supported by Internet Explorer.
