Shouldn't you be minimizing your CSS (and JavaScript) as part of a deployment script, anyway? This tool supports sourcemaps, so it will show you the original CS

Shouldn't you be minimizing your CSS (and JavaScript) as part of a deployment script, anyway? This tool supports sourcemaps, so it will show you the original CSS. My major issue with it is that it doesn't seem to take media queries into consideration. It marked as unused a number of styles wrapped in a min-width that happened to be larger than my browser window. Without automation, it's going to be time-consuming to click through every page of a site and resize the browser window from very small to very large.
