Remove white space / header above featured header image

Here is my website http://www.vetsimulators.com I am trying to remove the white block / header that is above my featured header image. I know it has to do with hgroup wrap and my header-sidebar-widget-area I have tried entering all of these in the custom css area with no success. { #hgroup-wrap { display: none; } #header-content { padding: 40px 0; } #header-content { padding: 0px 0; } #header-content { display: none; } Any help??
