是否可以将 div 样式设置为梯形?

我知道可能会倾斜,但我没有找到一种方法可以使每个角倾斜特定的角度。

这是我正在从事的项目: http://map.ucf.edu/

具体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。

我知道可以创建一个 CSS trapazoid,但是即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 我能够实现这一目标: 演示

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; }

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; }

这是可能的,这是粗略的想法:

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>

<div>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Etiam cursus ex quis enim posuere auctor.</div>

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>

<div>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Etiam cursus ex quis enim posuere auctor.</div>

我们可以使用 linear-gradient() 在矩形元素上绘制梯形形状。

这个技巧使用了将整个形状分成不同部分的想法,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;
}
<div>
  Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... 
</div>

<div>

We can use linear-gradient() to draw trapezoidal shape on rectangular element.

This trick uses the idea of dividing whole shape in different parts and then draws each shape on the background independently.

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;
}
<div>
  Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... 
</div>

<div>
  Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... Lorem ipsum dolor sit amet... 
</div>

现在,您可以使用 clip-path 和 多边形
剪辑路径和多边形计算

.rectangle {
  width: 400px;
  height: 200px;
  background-color: red;
  clip-path: polygon(15% 0, 85% 0, 100% 100%, 0% 100%);

}
<div class="rectangle"></div>

在这个例子中我们有 4 个参数。

第一个参数(左上)

x -> 15%
y-> 0

第二个参数(右上角)

x -> 85%
y-> 0

第三个参数(右下)

x -> 100%
y-> 100%

第四个参数(左下)

x -> 0
y-> 100%

Now, you can achieve that pretty straightforward with clip-path and polygon
Clip Path and Polygon calculations

.rectangle {
  width: 400px;
  height: 200px;
  background-color: red;
  clip-path: polygon(15% 0, 85% 0, 100% 100%, 0% 100%);

}
<div class="rectangle"></div>

In this example we there are 4 parameters.

First parameter ( Top left )

x -> 15%
y -> 0

Second parameter ( Top right )

x -> 85%
y -> 0

Third parameter ( Bottom right )

x -> 100%
y -> 100%

Fourth parameter ( Bottom left )

x -> 0
y -> 100%
