I want to expand the hero image for 100% of the browser HEIGHT.
This is what I have:
.home-splash {
    position: relative;
    display: table;
    width: 100%;
    height: 100%;
    background: url("http://www.matthewkosloski.me/hero-3a.jpg") center center;
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -ms-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
}
With this code, the hero image (or splash image) only expands to the height of the header.  However, this problem can be avoided (somewhat) by using width: 100vh;.  I don't like that because on mobile devices, the height of the hero image is really large... like 5000px in height.  I just want it to expand the EXACT height of the browser.
