如何为没有边框的图标添加渐变颜色

Question

我想制作一个喜欢的图标，我想在悬停时用渐变色完全填充一个图标，没有边框只有心形。我用 fontawesome.

html:

                    <i class="far fa-heart"></i>

sass:

        i{
        position: absolute;
        left: 70vmin;
        top:2vmin;
        font-size: 1.6em;
        z-index: 100;
        cursor: pointer;
        font-weight: 100;
        &:hover{
            transition: all .8s ease-in-out;
            -webkit-background-clip: text;
            font-weight: 900;
            background-image: linear-gradient($color-primary, $color-secondary);
            -webkit-text-fill-color: transparent;
        }

我看到很多人用background-clip 和text-fill-color 只是图标不见了。

有什么解决办法吗？

谢谢

你可以这样实现：

i{
  position: absolute;
  left: 70vmin;
  top:2vmin;
  font-size: 1.6em;
  z-index: 100;
  cursor: pointer;
  font-weight: 100;
}   
i:hover:before{
  transition: all .8s ease-in-out;
  -webkit-background-clip: text;
  font-weight: 900;
  background-image: linear-gradient(red, yellow);
  -webkit-text-fill-color: transparent;
}
