Reply To: Vertikal centering responsive bootstrap div

[Merri]

With no changes to HTML:

html {
    display: table;
    height: 100%;
    width: 100%;
}

body {
    display: table-cell;
    padding-top: 90px; /* .navbar height */
    vertical-align: middle;
}

.navbar {
    position: absolute;
    left: 0;
    top: 0;
    width: 100%;
}

And you may be lucky enough to see it working on IE8 as well.
