I’m really enjoying GP, and I have my first question: I like the way the featured images appear on the Home/front page, but I would like them to not show on the single post page. Especially if the featured image is a small file, and it gets ‘blown up’ on the single post page: http://www.windowstalk.org/2014/08/pdferaser-giveaway/
Ben, instead of editing your style.css file, you will find it best to use the Simple Custom CSS Plugin. http://wordpress.org/plugins/simple-custom-css/
That way, when the theme is updated, you won’t lose your modifications.
