I am very new to Front-end development and Foundation.
I am trying to get <div class="main-header"> to be a full screen image that scales down responsively. 
Can anyone tell me what I am doing wrong? It is scaling properly, but is not showing the full image. I also wanted the <div class="large-6 large-offset-6 columns"> to sit above it on a mobile device – is that possible?
The HTML:
<!-- MAIN HEADER -->
<div class="main-header">
   <div class="row">
     <div class="large-6 large-offset-6 columns">
       <h1 class="logo">BleepBleeps</h1>
       <h3>A family of little friends<br>that make parenting easier</h3>
     </div> <!-- END large-6 large-offset-6 columns -->
   </div><!-- END ROW -->
</div><!-- END MAIN-HEADER -->
The CSS:
.main-header {
    background-image: url(../img/bb-background2.png);
    background-repeat: no-repeat;
    background-position: center;
    background-size: cover;
    width: 100%;
    height: 100%;
}
h1.logo {
    text-indent: -9999px;
    height:115px;
    margin-top: 10%;
}
