CSS的一侧偏斜

Question

我想创建一个单侧偏斜，但是没有这样做。 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：

我要完成的工作：

Answer 1

将overflow:hidden到.bg-style1规则中，并将transformX(-40%)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. </div> </section> 

Answer 2

是您的问题是因为父母背景出现在倾斜块的左侧。 如果是，则应使用transform-origin: 0 0;

  .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); transform-origin: 0 0; } 

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