css - 单边倾斜与CSS

Question

我想创建一个单边倾斜，但没有成功。到目前为止，这是我尝试过的:

    .bg-style1 {
      background: #ccc;
      position: relative;
      display: block;
      z-index: 2;
    }
    .bg-style1:after {
      content: " ";
      position: absolute;
      display: block;
      width: 30%;
      height: 100%;
      top: 0;
      left: 0;
      z-index: -1;
      background: #333333;
      -ms-transform: skew(-30deg, 0deg);
      -webkit-transform: skew(-30deg, 0deg);
      transform: skew(-30deg, 0deg);
    }

<section class="page">
  <div class="bg-style1">
    .....content goes here
  </div>
</section>

但它不起作用。看:

我想完成的事情:

将 overflow:hidden 添加到您的 .bg-style1 规则并将 transformX(-40%) 添加到 transform: 在 .bg-style1:after

.bg-style1 {
  padding-top: ;
  background: #ccc;
  position: relative;
  display: block;
  z-index: 2;
  overflow: hidden;
}
.bg-style1:after {
  content: " ";
  position: absolute;
  display: block;
  width: 30%;
  height: 100%;
  left: 0;
  top: 0;
  z-index: -1;
  background: #333333;
  -ms-transform: skew(-30deg, 0deg);
  -webkit-transform: skew(-30deg, 0deg);
  transform: skew(-30deg, 0deg) translateX(-50%);
}

<section class="page">
  <div class="bg-style1">
    <h1>What is lorem ipsum</h1>
    Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has
    survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing
    software like Aldus PageMaker including versions of Lorem Ipsum.
