Adding a class for the example is not only ugly, it's fragile -- customizations to the actual threshold will have no effect on the sample.
The sensible thing is to construct an actual bit of sample text using the actual classes -- a null link (<a href="#">) with appropriate class would show the effect nicely and be robust to customizations.
