CSS3 Transform Skew One Side

Question

Is it possible to create "CSS3 Transform Skew One Side"

I found one solution, but it's not useful to me, because I need to use a image for background (not color)

#skewOneSide {
    border-bottom: 40px solid #FF0000;
    border-left: 50px solid rgba(0, 0, 0, 0);
    height: 0;
    line-height: 40px;
    width: 100px;
}

Even this JsFiddle is not useful as well (skewed area should be transparent)

Answer 1

Try this:

To unskew the image use a nested div for the image and give it the opposite skew value. So if you had 20deg on the parent then you can give the nested (image) div a skew value of -20deg.

.container {
  overflow: hidden;
}

#parallelogram {
  width: 150px;
  height: 100px;
  margin: 0 0 0 -20px;
  -webkit-transform: skew(20deg);
  -moz-transform: skew(20deg);
  -o-transform: skew(20deg);
  background: red;
  overflow: hidden;
  position: relative;
}

.image {
  background: url(http://placekitten.com/301/301);
  position: absolute;
  top: -30px;
  left: -30px;
  right: -30px;
  bottom: -30px;
  -webkit-transform: skew(-20deg);
  -moz-transform: skew(-20deg);
  -o-transform: skew(-20deg);
}

<div class="container">
  <div id="parallelogram">
    <div class="image"></div>
  </div>
</div>
