Move Social Links and Spacing

Hi, I found a post previously about moving the social link in the header area. But the custom CSS  i entered doesn't appear to do anything. I wanted to move the social links above my Logo and reduce the spacing. Here is the website: www.tpsukpodcast.com The CSS was: #header .social-search {margin-top: 20px;} #header .logo-wrap { margin-top: 30px; } #header #mainmenu { margin-top: 30px; } This is the content of my total Custom CSS  Style: #header .social-search form.searchform {display: none;} #main #content .post h2.entry-title { font-size: 20px; line-height:25px; } #add_image_size( 'featured', 100, 100, true); // uses on homepage featured image #header .social-search {margin-top: 20px;} #header .logo-wrap { margin-top: 30px; } #header #mainmenu { margin-top: 30px; } Thanks Zonal
