Remove featured article space from home

Hello!
This is our site: elfuturo.eu
We dont need the white space under the slider (for the featured post)
How can we remove it?

add this to bottom of template_css.css:

.nocontent {
display: none;
}

then in home page menu item for page class field in right panel settings put
" nocontent"

Not working

add this at bottom of head section in index.php of template:

<script type="text/javascript">
jQuery(document).ready(function(){
jQuery('.blog-featurednocontent').parent().parent().parent().hide();
});
</script>

Still not working
