我正试图将游标属性设置为 cursor: pointer 并增加 font-size 使用 :hover 上 .btn_one 和 .btn_two 。这些属性正在应用于 .btn_two 但不是 .btnone .

我在多个平台上搜索了如何解决这个问题,但找不到相关的解决方案。

有人能解释一下这背后的原因吗?

您只需使用tatgeting.btn_two即可获得悬停效果 .sidebar_menu .btn_two i:hover{ font-size: 30px; }

你需要针对这两个类。

 .btn_one i{
   position: absolute;
   z-index: 1;
   color: white;
   font-size: 25px;
   font-weight: 900;
   left: 16px;
   line-height: 60px;
   cursor: pointer;
 }

.btn_one i:hover, .btn_two i:hover{
   font-size: 30px;
  }
