html - 将文本放在绝对定位的 div 的中心

Question

在下面的 html 片段中，我尝试将文本放在绝对定位的 div 的中心，类 featured-price。但是 span 中带有类 centerd 的文本在 div 中是不可见的。我正在使用 **materialize css ** 框架进行开发。

.review-star{
  color: #20BF55;
}
.featured-price{
  display: table;
  bottom: 15px;
  left: 0;
  padding: 3px 10px 2px 10px;
  font-size: 16px;
  height: 180px;
  position: absolute;
  background-color: #FF5964;
  -webkit-clip-path: polygon(0 80%, 100% 80%, 100% 100%, 0% 100%);
  clip-path: polygon(0 80%, 100% 80%, 100% 100%, 0% 100%);
  .centerd{
    color:white;
  }  
}

如果有人能打印出我在上面犯的错误，我将不胜感激。

Answer 1

将 .featured-price 类的高度 180px 更改为 60px，如下所示，并删除 clip-path

    .featured-price{
       height:60px;
      /* -webkit-clip-path: polygon(0 80%, 100% 80%, 100% 100%, 0% 100%);
       clip-path: polygon(0 80%, 100% 80%, 100% 100%, 0% 100%); remove this clip-path*/
    }
