at http://social.clipflair.net I see in page source

<style type="text/css" media="screen"> { display:block; } .MonoXSimpleMenu .level0,  { display:none; } </style><style type="text/css">
 .ctl00_ctl00_ctl01_ctl00_cp_cp_cp_cp_leftPartZone_0 { border-color:#D1DDF1;border-width:1px;border-style:Solid; }
 .ctl00_ctl00_ctl01_ctl00_cp_cp_cp_cp_leftPartZone_1 {  }
 .ctl00_ctl00_ctl01_ctl00_cp_cp_cp_cp_leftPartZone_2 { color:White;font-family:Arial;font-size:10px;font-weight:bold; }
 .ctl00_ctl00_ctl01_ctl00_cp_cp_cp_cp_leftPartZone_3 { background-color:#507CD1; }</style>

I think this is added by MonoX and the issue is that {display:block;} rule should have a selector before it (if you use Mozilla Firefox Web Developer toolbar it has a Web Console that shows such errors)
