My current theme places a white background behind the content of pages and blog posts. However, it makes the background of all widgets in my sidebars transparent. With my current website background, this makes it hard to read the content of widgets, especially on my homepage, where most of the content is in widgets. I'd rather try changing the background of the widgets before I change the site's background.
