Answer 1

CSS:

#box {
    width: 200px;
    height: 200px;
    background: black;
    position: relative;
    -webkit-transition: all 300ms ease-in;
}
#box:hover {
    -webkit-transform: rotate(-180deg) scale(0.8);
}
#box:after, #box:before {
    display: block;
    content: "020";
    color: transparent;
    width: 211px;
    height: 45px;
    background: white;
    position: absolute;
    left: 1px;
    bottom: -20px;
    -webkit-transform: rotate(-12deg);
    -moz-transform: rotate(-12deg);
}
#box:before {
    bottom: auto;
    top: -20px;
    -webkit-transform: rotate(12deg);
    -moz-transform: rotate(12deg);
}?

HTML:

<div id=box></div>?
