Is it possible to make an if conditional dependent on the styleid?

I'm trying to show different content in a sidebar widget dependent on the style. Is this possible to do using if conditionals?

I might be way off, but I tried something like:

<xen:if is="{xen:helper styleid=2}">
Content 1
<xen:else />
Content 2

But that didn't work.

Any help is greatly appreciated!
