仅在悬停时转换为边框,但不适用于背景

Question

这里我有一些CSS:

    #image-edges-beneath:hover{
    background-color: blue;
    }

    #image-edges:hover{
      background-color: blue;
    }

    #image-edges-beneat:hover:after{
    -webkit-transition: all 1s ease;
         -moz-transition: all 1s ease;
           -o-transition: all 1s ease;
          -ms-transition: all 1s ease;
              transition: all 1s ease;
      border: 2px solid #F1FD6D;
    }

    #image-edges:hover:after{
    -webkit-transition: all 1s ease;
         -moz-transition: all 1s ease;
           -o-transition: all 1s ease;
          -ms-transition: all 1s ease;
              transition: all 1s ease;
      border: 2px solid #F1FD6D;
    }

但这不起作用.唯一发生的事情是背景颜色有一个过渡,而我希望它只在悬停时改变,而边框我想要一个过渡,所以基本上边框渐渐变成颜色,而背景颜色在悬停时立即改变颜色.这就是我想要完成的,但这不起作用.:(任何想法用户？

Answer 1

您需要做的是设置要正确转换的属性.目前你把它作为"全部",但它需要是"背景颜色"或"边框颜色",根据你想要转换它.

 transition: border-color 1s ease;

您可以通过多种方式进行边框效果。将以下CSS应用于要应用边框效果的类，并在发生任何事件时更改边框样式。

 -webkit-transition:  border 3s ease;
 -moz-transition:  border 3s ease;
 -o-transition:  border 3s ease;
 -ms-transition: border 3s ease;
 transition: border 3s ease;
