Hi there!
I’m trying to create a very clean, simple site however I’ve become completely stuck in simply trying to remove the border separating the header and body, and in making the background of my posts transparent. Here’s what I’m talking about:

I’m using the integrity stack, and am using the following custom CSS to make all other backgrounds on the site transparent:
.x-navbar {
background-color: rgba(0,0,0,0.0) !important;
position: absolute;
width: 100%;
}
.x-navbar .x-nav-wrap .x-nav > li > a {
color: #fff;
}
.x-navbar {
border-bottom: transparent;
}
.x-logobar {background-color: transparent;} /*logo bar*/
.x-navbar {background-color: transparent;} /*nav bar*/
.x-colophon {background-color: transparent;} /*footer*/
@media ( min-width: 980px ) {
.x-navbar {
display:none;
}
}
.page-inner-title {
background-color: transparent;
}
@media (max-width: 979px){
body .x-navbar-wrap {
display:none !important;
}
}
.jumbo-menu-button {
width: 72px !important;
}
.format-standard .entry-wrap {
color: #fff !important;
background-color: #000 !important;
}
header.entry-header {
display: none;
}
The site is fortunepoems.com (currently under construction). I fear I’m missing something very easy and obvious… please help!
