I\'ve got a height and width, and overflow:hidden so that specfic inner images are clipped
You can overflow an element out of the div by wrapping it in another div, then set your image as position:absolute; and offset it using margins.
.no-overflow{
overflow:hidden;
width: 500px
height: 100px
}
.escape{
position: absolute;
margin-bottom: -150px;
}
