CSS3 Transform Skew One Side

Maybe you want to use CSS "clip-path" (Works with transparency and background)

"clip-path" reference: https://developer.mozilla.org/en-US/docs/Web/CSS/clip-path

Generator: https://bennettfeely.com/clippy/

Example:

/* With percent */
.element-percent {
  background: red;
  width: 150px;
  height: 48px;
  display: inline-block;
  
  clip-path: polygon(0 0, 100% 0%, 75% 100%, 0% 100%);
}

/* With pixel */
.element-pixel {
  background: blue;
  width: 150px;
  height: 48px;
  display: inline-block;
  
  clip-path: polygon(0 0, 100% 0%, calc(100% - 32px) 100%, 0% 100%);
}

/* With background */
.element-background {
  background: url(https://images.pexels.com/photos/170811/pexels-photo-170811.jpeg?auto=compress&cs=tinysrgb&dpr=2&h=750&w=1260) no-repeat center/cover;
  width: 150px;
  height: 48px;
  display: inline-block;
  
  clip-path: polygon(0 0, 100% 0%, calc(100% - 32px) 100%, 0% 100%);
}
<div class="element-percent"></div>

<br />

<div class="element-pixel"></div>

<br />

<div class="element-background"></div>

you can make that using transform and transform origins.

Combining various transfroms gives similar result. I hope you find it helpful. :) See these examples for simpler transforms. this has left point :

This has right skew point :

div {    
    width: 300px;
    height:200px;
    background-image: url('data:image/gif;base64,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');
    -webkit-transform: perspective(300px) rotateX(-30deg);
    -o-transform: perspective(300px) rotateX(-30deg);
    -moz-transform: perspective(300px) rotateX(-30deg);
    -webkit-transform-origin: 0% 50%;
    -moz-transform-origin: 0% 50%;
    -o-transform-origin: 0% 50%;
    transform-origin: 0% 50%;
    margin: 10px 90px;
}
<div></div>

what transform: 0% 50%; does is it sets the origin to vertical middle and horizontal left of the element. so the perspective is not visible at the left part of the image, so it looks flat. Perspective effect is there at the right part, so it looks slanted.


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>
