Disable links to posts from featured images

Hi, I'm looking to remove the links to posts from the features images on the home page. My test site is at www.stevefitzgerald.net/magoffinhall. This is probably temporary. Also, I want to reduce the header size. I've added the following custom CSS but it's not reducing the size enough. Suggestions? .home #main { padding: 0; } #hgroup-wrap { padding-left: 2px;padding-top: 0;padding-top:3rem; padding-bottom: 0; } #site-logo {padding-top: 0; padding-top: 3rem;} #header-content {padding-top: 0;padding-top: 0rem;}
