Where #feature is the element that you want to be full height.

``` jQuery(document).ready(function(){ resizeDiv(); });

window.onresize = function(event) { resizeDiv(); };

function resizeDiv() { vpw = $(window).width(); vph = $(window).height(); jQuery(‘#feature’).css({‘height’: vph + ‘px’}); } ```

The CSS (flexbox)

#feature {
    height: 100%;
    display: flex;
    align-items: center;
}
