For styling, we have a full system built-in to SCLogin where you can create your own CSS theme and make any modifications you need to suit your site. For more information, see our theming guide:
www.sourcecoast.com/sclogin/documentation/themes
As for your specific request, can you let us know more about what you're trying to do? What demo page of ours are you referring to? You mention your template's login form, but without a link or picture, I don't know what that looks like either.
In general, we can try to give pointers on styling, but every template is different. There's only so much assistance we can provide to make styles suit every site. Of course, if you're running into any functional issues, we'll gladly help however we can.
Thanks,
Alex
