是否可以将图像添加为框阴影，例如将图像添加为点而不是标准阴影？

Answer 1

你想要这样的东西吗？它不完全是box-shadow，但它模仿它。 您可以为background设置.image::after所需的任何图像。

＆＃13;

＆＃13;

html, body {
  margin: 0;
}
body {
  width: 100vw;
  height: 100vh;
}
.contain {
  width: 100%;
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
}
.image{
  position: relative;
  width: 200px;
  height: 200px;
  background-image: url(http://via.placeholder.com/200x200);
}
.image::after {
  content: '';
  background: linear-gradient(to bottom, #333, red);
  position: absolute;
  width: 100%;
  height: 100%;
  bottom: -10px;
  right: -10px;
  z-index: -1;
}

＆＃13;

<div class="contain">
  <div class="image"></div>
</div>

＆＃13;

我认为这正是您所寻找的：

body {
        background: black;
    }
    
    #logo {
        width: 200px;
        height: 200px;
        display: block;
        position: relative;
    }
    
    #logo::after {
        content: "";
        background: url("https://rfclipart.com/image/big/3f-a9-1a/red-dotted-halftone-background-Download-Royalty-free-Vector-File-EPS-183199.jpg");
        opacity: 0.4;
        top: 0;
        left: 0;
        bottom: 0;
        right: 0;
        position: absolute;
        border-radius: 50%;
        z-index: -1;
    }
    
    img {
        width: 90%;
        height: 90%;
        padding: 5%;
        display: block;
        float: left;
        border-radius: 50%;
        box-shadow: 0px 0px 40px #ccc;
        -moz-box-shadow: 0px 0px 40px #ccc;
        -webkit-box-shadow: 0px 0px 40px #ccc;
    }

<div id="logo">
    <img src="http://icons.iconarchive.com/icons/graphicloads/colorful-long-
    shadow/256/User-icon.png" alt=""/>
    </div>

    

Answer 3

有点像this？

.image_carousel img {
  margin-right: 14px;
  display: block;
  float: left;
  box-shadow: 3px 3px 1px #ccc;
  -webkit-box-shadow: 3px 3px 1px #ccc;
  -moz-box-shadow: 3px 3px 1px #ccc;
}

<div class="image_carousel"><img src="//placehold.it/300/f80/fff" alt=""/></div>
