UPDATE:

Here is an example and the result code: jsFiddle.

<style type="text/css">
#trapezoid {
    height: 0;
    width: 100px;
    border-bottom: 100px solid red;
    border-left: 50px solid transparent;
    border-right: 50px solid transparent;
}
</style>
<div id="trapezoid"></div>

This will create a trapezoid.

Or this:

<style type="text/css">
#parallelogram {
    width: 150px;
    height: 100px;
    -webkit-transform: skew(20deg);
       -moz-transform: skew(20deg);
         -o-transform: skew(20deg);
    background: red;
}
</style>
<div id="parallelogram"></div>

This will create a parallelogram
