CSS Question

Is it possible to style a div to be trapezoidal?

I know it's possible to skew but I don't see a way to skew each corner with a particular degree.

Here's the project I'm working on: http://map.ucf.edu/

Looking specifically at the tabs within the menu. Right now I'm using images, I would like to change that for capable browsers.

I know it's possible to create a CSS trapazoid, but that is using borders without content. The end result also needs a bit of rounded corners.

edit:
Starting with Zoltan Toth's solution I was able to achieve this: demo

div {
height: 20px;
padding:2px 5px 0 5px;
color:white;
background: rgba(0,0,0,.5);
margin: 0 10px;
position: relative;
border-top-left-radius: 6px 4px;
border-top-right-radius: 6px 4px;
font-family:sans-serif;
font-size:13px;
line-height:20px;
vertical-align:bottom;
display:inline-block;
white-space:nowrap;
}

div:before {
content: '';
line-height: 0;
font-size: 0;
width: 0;
height: 0;
border-bottom: 19px solid rgba(0,0,0,.5);
border-left: 9px solid transparent;
position: absolute;
bottom: 0;
left: -9px;
}

div:after {
content: '';
line-height: 0;
font-size: 0;
width: 0;
height: 0;
border-bottom: 19px solid rgba(0,0,0,.5);
border-right: 9px solid transparent;
position: absolute;
bottom: 0;
right: -9px;
}

.b { background:black; margin:0 -7px 0 20px; }
.b:after, .b:before { border-bottom-color:black; }

Answer

It is possible, here is the rough idea:

div {
    width: 200px;
    height: 100px;
    background: #ddd;
    margin: 20px 150px;
    position: relative
}

div:before {
    content: '';
    line-height: 0;
    font-size: 0;
    width: 0;
    height: 0;
    border-top: 50px solid transparent;
    border-bottom: 50px solid #ddd;
    border-left: 50px solid transparent;
    border-right: 50px solid #ddd;
    position: absolute;
    top: 0;
    left: -99px;
}

div:after {
    content: '';
    line-height: 0;
    font-size: 0;
    width: 0;
    height: 0;
    border-top: 50px solid transparent;
    border-bottom: 50px solid #ddd;
    border-left: 50px solid #ddd;
    border-right: 50px solid transparent;
    position: absolute;
    top: 0;
    right: -99px;
}
<div>Hello</div>
