shape-outside 属性根本不起作用

Question

我刚刚开始尝试 css 中的 shape-outside 属性，但无论我浏览了多少文档或博客，我都无法使其正常工作。我可能犯了一个愚蠢的错误，但我不确定。谁能指出错误？

#q {
  background-color: #E6C9C9;
  /*height: 100%;
 width: 100%;*/
  float: left !important;
  -webkit-shape-outside: circle(50%);
  shape-outside: circle(50%);
}

Answer 1

您不能在元素本身上使用 outside-shape，但可以使用 :before 或 :after 伪元素向元素添加 outside-shape .请参阅以下使用 :before 的解决方案：

#q:before {
  content:"";
  display:block;
  height:300px;
  width:300px;
  float: left;
  -webkit-shape-outside: circle(50%);
  shape-outside: circle(50%);
}
#q {
  background-color: #E6C9C9;
}
