Use calc method (http://jsfiddle.net/ATcpw/2/):

.block{
    position:absolute;
    top: -webkit-calc(100% - 110px);
    right:10px;
    left:10px;
    height:100px;
    background:gray;
    -webkit-transition: all 2s;
    /*this adds GPU acceleration*/
    transform: translate3d(0,0,0); 
    -webkit-transform: translate3d(0,0,0);
}
.block.hide{
    top: -100px;
}

Since you are using -webkit prefix I used it as well. calc is supported by majority of browsers: http://caniuse.com/#search=calc
