#main-footer::before {    content: " ";    background: url("/bottom.png") no-repeat;    background-size: 100%;    width: 100%;    min-width: 100%;    display: block;    position: absolute;    height: 140px;    bottom: 0; }

but element hang somewhere in middle of website. can please me understand why , im doing wrong here ? here url : http://webconcept.hekko24.pl/mr/
