Highlighting admin comments in the Responsive theme

One thing I like about some blogs is that you can easily see when the admin has replied to comments. It is easy to tweak the Responsive theme to change the colour of these comments by including a few lines of CSS. Click on “Appearance -> Theme Options” in the WordPress admin section, then expand the “Custom CSS Styles” section. You should put the CSS here instead of editing the theme because it will persist when you upgrade the theme.
