Sorry, didn't realise you were using themes here. The general format for that is: .portable-infobox.pi-theme-name .pi-title { background: purple; } However, for the three things you're wanting to style — titles, navigation and headers — you can usually drop the, like this: .pi-theme-name .pi-title, .pi-theme-name .pi-navigation, .pi-theme-name .pi-header { background:purple; } Note that commas separate entire selectors, so they come at the very end — not between the parent and child selectors. You also don't typically need to specifiy. Just  will usually do. You can read more about that, though, by searching for "css background" on the web.
