As of now Q2A has a single sidebar and most widget plugins use that. But one issue is that there is no standard for layout being used for the widget title and hence it is difficult to apply any CSS theme which is kind of uniform across the plugins. To make this clear, what I meant is all sidebar widgets to agree upon a same "<div class>" for widget title. I see many of them using "<h2>". Can this be taken as a standard and used in widget plugins?
I have seen the plugin tutorial, but could not find any standard way to have the plugin layout or CSS styling which would work well with the standard themes. Am I missing something?
