Not yet, no. It wraps a good few elements round each form control by
itself though, most of which have classes and IDs, so can be styled as
required. The comment forms on my website are one example.

Mine is entirely intended for data validation. You can't reasonably do
much more with it because it only operates on a single field -- not the
whole form.
When the form has been submitted you call:
$ok = $form->accept_submission() && $form->validate();
then the DBF_Form object will read submitted data and validate each field
in turn. Then you can call:
$vals = $form->get_values();
which returns an array of validated values, and you can do with that what
you want (e-mail it, store it in a database, etc).
