Problems with CSS for .wp-smiley

Hello Support, I'm trying to change the border around smileys at Your theme. I've tried in various ways but behaviour (border: 1px) is always inherited from #main #content img not from: 1. Custom CSS in Appearance 2. Custom CSS inside Simple Catch theme options 3. .wp-smiley {} inside the style.css of Your theme I've tried code: <code>.wp-smiley {border: 0}</code> and <code>img.wp-smiley {border: 0}</code> and <code>#main #content .wp-smiley {border:0}</code> Please advise.
