Apologies, I realized this morning this belongs in the support forum of the theme (fresh-editorial), not the widget.
One thing to note: there are a lot of people complaining about not being able to apply CSS rules to their modules. It may be the case that the theme is not correctly rendering the widgets. If you do not see a “widget_twitter” class in the html document, the theme is not rendering the widget correctly. FYI. That is clearly what was going on here.
