带有背景图像的 CSS 插入文本阴影

Question

是否可以让文字同时带有背景图片和内阴影？

div{   
    position:fixed;
    z-index: 2;
    color: white;  /* Fallback: assume this color ON TOP of image */
    background: url('https://placekitten.com/g/500/500') repeat;
    -webkit-background-clip: text;
    -webkit-text-fill-color: transparent;
    font-size: 100px;
    font-weight: 800;
    text-transform: uppercase; 
    text-shadow: 2px 3px 8px rgba(59, 37, 17, 0.35) inset; 
}

<div>
  CAN I HAVE AN IMAGE AND INNER SHADOW?
</div>

Answer 1

使用 CSS 过滤器属性，您可以添加轮廓为任何形状的阴影:

div{   
    position:fixed;
    z-index: 2;
    color: white;  /* Fallback: assume this color ON TOP of image */
    background: url('https://placekitten.com/g/500/500') repeat;
    -webkit-background-clip: text;
    -webkit-text-fill-color: transparent;
    font-size: 100px;
    font-weight: 800;
    text-transform: uppercase; 
    text-shadow: 2px 3px 8px rgba(59, 37, 17, 0.35) inset; 
    filter: drop-shadow( 10px 10px 10px #888 );
}

<div>
  CAN I HAVE AN IMAGE AND INNER SHADOW?
</div>

所有主流浏览器现在都支持基本的过滤器! http://caniuse.com/#feat=css-filters

对于嵌入阴影

嵌入阴影需要一些技巧。

我的方法是直接在第一个 div 之上添加另一个具有透明文本不透明度的 div。然后我们使用文本阴影 hack 使其看起来像是嵌入的。

.regular {
    position:fixed;
    z-index: -1
    color: white;  /* Fallback: assume this color ON TOP of image */
    background: url('https://placekitten.com/g/500/500') repeat;
    -webkit-background-clip: text;
    -webkit-text-fill-color: transparent;
    font-size: 100px;
    font-weight: 800;
    text-transform: uppercase; 
    text-shadow: 2px 3px 8px rgba(59, 37, 17, 0.35) inset; 
}
.overlay {
    position:fixed;
    z-index: 10;
    color: transparent;
    font-size: 100px;
    font-weight: 800;
    text-transform: uppercase; 
    text-shadow: 2px 2px 3px rgba(255,255,255,0.5);
    -webkit-background-clip: text;
       -moz-background-clip: text;
            background-clip: text;
}

<div class="regular">
  CAN I HAVE AN IMAGE AND INNER SHADOW?
</div>
<div class="overlay">
  CAN I HAVE AN IMAGE AND INNER SHADOW?
</div>
