I can't believe I'm asking such a basic question! I normally style my own sidebar but for this website I am using widgets instead. I'm using the RSS widget but can't work out how to change the background colour.
When I use Firebug I notice that the HTML structure gives every widget the ID 'widget', so they are all generic and don't have their own CSS classes.
With this in mind, how am I supposed to change the bgcolor of one widget in particular?
