CSS Transform to skew the shape to a trapezium

Question

I want to be able to skew an element in the way the image displays below.

I have been playing around with it, but dont seem to be able to get close to replicating that shape.

My css code is

transform:skew(30deg,30deg);

Is transform even the right way to do this? Please let me know the best, most browser compatible, solution.

Answer 1

You can apply some rotate transform around the X axis and apply an appropriate pespective before:

div {    
  width:300px;
  height:200px;
  background:url(http://placekitten.com/300/200);
  border:2px solid red;    
  border-top-width:4px;
  border-bottom-width:1px;
  -webkit-transform: perspective(200px) rotateX(40deg);    
  margin:100px;
}
