Unlike most themes, Circumference stands out by offering you several widget styles that you can use to enhance the overall look and style of your web pages by assigning styles to your widgets. These styles are not just for text widgets, they can be used on almost any widget that you have in your site. Adding styles is easy, and all you have to do is install a plugin called Widget CSS Classes, and then you are ready to go in style!
You can apply different colours by adding a class named by the colour. Grey is the default colour, but you also get: Aqua Brown Tan Red Orange Green
