我知道倾斜是可能的，但我看不到一种方法可以使每个角落倾斜特定的角度。

这是我正在进行的项目：http: //map.ucf.edu/

专门查看菜单中的选项卡。现在我正在使用图像，我想为有能力的浏览器更改它。

我知道可以创建CSS 梯形，但这是使用没有内容的边框。最终结果还需要一些圆角。

编辑：从Zoltan Toth 的解决方案开始，我能够做到这一点：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; }

这是可能的，这是一个粗略的想法：

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>

我们可以使用linear-gradient()在矩形元素上绘制梯形。

这个技巧使用将整个形状划分为不同部分的想法，然后在背景上独立绘制每个形状。

div {
  background-image:
   linear-gradient(to bottom right, transparent 50%, silver 50%), /* draws left part */
   linear-gradient(to bottom left, transparent 50%, silver 50%), /* draws right part */
   linear-gradient(to right, silver, silver); /* draws central flat part */

  background-repeat: no-repeat;

  /* Sets the background size of each of three shapes individually */
  background-size: 75px 100%, 75px 100%, calc(100% - 150px) 100%;

  /* Sets the background position of each of three shapes individually */
  background-position: 0 0, 100% 0, 75px 0;
}


body {
  background: linear-gradient(orange, red) no-repeat;
  min-height: 100vh;
  margin: 0;
}

div {
  background-image: linear-gradient(to bottom right, transparent 50%, silver 50%),
    linear-gradient(to bottom left, transparent 50%, silver 50%),
    linear-gradient(to right, silver, silver);

  background-size: 75px 100%, 75px 100%, calc(100% - 150px) 100%;
  background-position: 0 0, 100% 0, 75px 0;
  background-repeat: no-repeat;

  padding: 20px 80px;
  min-height: 80px;
  width: 300px;
  margin: 25px;
}
