更改阴影的大小而不是实际的 png

Change size of drop-shadow and not the actual png

我正在尝试在内部有图像的 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);
}
  <div class="grid">
    <div class="box8">
   <img src="https://pbs.twimg.com/profile_images/774007491130785792/hAtxoNuW_400x400.jpg" width="240" height="300">
  </div>

    </div>

试试这个: 即改变过滤器:drop-shadow to box-shadow

.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;
    box-shadow: 15px 25px 20px #222; /*this is changed*/
}

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怎么样?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;
}
