箱形与直角梯形

Question

我想知道这个形状是否可以用尽可能少的html在css3中完成:

到目前为止,我已成功地做到了这一点:

.wrapper {
  position: relative;
}
.box {
  width: 100px;
  height: 100px;
  border: 1px solid #000;
  position: absolute;
  top: 100px;
  left: 100px;
}
.box:before {
  content: "";
  border: 1px solid #000;
  border-bottom: 1px solid #fff;
  width: 50%;
  height: 10px;
  position: absolute;
  top: -12px;
  left: -1px;
}
.box:after {
  content: "";
  border: 1px solid #000;
  border-top: 1px solid #fff;
  width: 50%;
  height: 10px;
  position: absolute;
  bottom: -12px;
  right: -1px;
}

<div class="wrapper">
  <div class="box"></div>
</div>

小提琴在这里,但我不知道如何扭曲这样,以便我在顶部和底部有直角梯形.

Answer 1

形状不需要额外的元素

可以使用以下命令创建形状<div>:

• 左侧是div,左边,上边和下边框.

• 右侧由:before顶部,右侧和底部边框构成

• 连接这两个盒子的跨度是在:after感谢的基础上创建的skewY

请注意转换属性的浏览器支持.IE 9需要-ms-前缀,Safari和Android浏览器需要-webkit-.

工作实例 - 只是形状

CSS已经压缩,伪元素的边框样式继承自div本身.

div {
  border: solid 4px #000;
  border-right-width: 0;
  width: 100px;
  height: 200px;
  position: relative;
}
div:before,div:after {
  content: '';
  display: block;
  height: 100%;
  width: 100%;
  border: inherit;
  border-right-width: 4px;
  border-left: none;
  position: absolute;
  left: 100%;
  top: 13px;
  margin-left: 20px;
}
div:after {
  width: 20px;
  border-right: none;
  top: 5px;
  transform: skewY(40deg);
  margin: 0;
}

<div></div>

工作示例 - 带文字

通过上面的示例,内容不会包含在整个形状中.相反,它将被限制在div半宽内.内容需要以<span>200%的宽度包装,以便在divs约束之外打孔.

div {
  border: solid 4px #000;
  border-right-width: 0;
  width: 100px;
  height: 200px;
  position: relative;
}
div:before,div:after {
  content: '';
  display: block;
  height: 100%;
  width: 100%;
  border: inherit;
  border-right-width: 4px;
  border-left: none;
  position: absolute;
  left: 100%;
  top: 13px;
  margin-left: 20px;
}
div:after {
  width: 20px;
  border-right: none;
  top: 5px;
  transform: skewY(40deg);
  margin: 0;
}
span {
  width: 200%;
  display: block;
  padding: 20px 10px 10px;
}

<div><span>This is me writing a large amount of words into the div. I think that you may want a span in order to contain them.</span></div>
