Eight of your frontend templates contain inline styles, which make it impossible to use custom css to change the settings. For example, I see this in filter_widget.inc.php and it is preventing me from adjusting the bottom margin for the line of buttons. Of course, I could manually edit your file, but that would require re-edits every time there is an update. Is this intentional? If so, it is poor practice, especially when the styles are for purely aesthetic characteristics such as margins.
