html - 更改阴影的大小而不是实际的 png

Question

我试图在内部有图像的 png 框架上放置阴影，但我不希望阴影覆盖图像。是否可以剪切或更改阴影的大小？

.grid {
  display: grid;
  }

.box8 { /*Girl*/
    grid-area: 1 / 1 / 1 / 1;
    margin: auto;
    z-index: -1;
}

.frame1 { /*Rectangular gold frame*/
    grid-area: 1 / 1 / 1 / 1;
    filter: grayscale(20%);
    margin: auto;
    -webkit-filter: drop-shadow(15px 25px 20px #222); /*Makes the shadow fit the png-image*/
    filter: drop-shadow(15px 25px 20px #222);
}

如何添加第二个框架实例，将其放在图片后面，并在该图片上添加阴影？这很骇人听闻，但它确实有效。像这样:

.grid {
  display: grid;
  }

.box8 { /*Girl*/
    grid-area: 1 / 1 / 1 / 1;
    margin: auto;
    z-index: -1;
}

.frame1 { /*Rectangular gold frame*/
    grid-area: 1 / 1 / 1 / 1;
    filter: grayscale(20%);
    margin: auto;
}

.frame2 { /*Rectangular gold frame*/
    grid-area: 1 / 1 / 1 / 1;
    filter: grayscale(20%);
    margin: auto;
    -webkit-filter: drop-shadow(15px 25px 20px #222); /*Makes the shadow fit the png-image*/
    filter: drop-shadow(15px 25px 20px #222);
    z-index:-2;
}
