We need a small adjustment on https://ezplatform.com/dkd

For the button:
a.btn:visited {
color: #63605d;
}

.btn.btn-outline {
border: 2px solid #63605d;
color: #63605d;
}

btn.btn-outline:hover {
background: #63605d;
border: 2px solid #63605d;
color: #fff;
}

and can we also make the page full height?
