jquery - 如何为网格中的图像添加内部阴影？

Question

我的脑袋疼，我无法让它工作

我正在尝试为这些盒子添加内部阴影，使它们看起来彼此分离 http://i.imgur.com/RlClNbh.png

http://jsfiddle.net/96d7udd7/

我试过这个

img { 
  box-shadow: inset 0px 0px 10px rgba(0,0,0,0.5);
}

但它只给标志一个内部阴影而不是盒子里的图像

这是盒子的HTML

    <figure class="imgbox">
        <img src="img/1.jpg" height="400px" alt="image01"/>
        <figcaption style="background: rgb(53, 25, 10)">
            <h2><span>Coffe Name</span></h2>
            <a href="#">View more</a>
        </figcaption>           
    </figure>

和 CSS

    figure.imgbox figcaption {
    box-shadow: inset 0px 0px 10px rgba(0,0,0,0.5);
    top: auto;
    bottom: 0;
    padding: 1em;
    height: 3.75em;
    background: #fff;
    color: #fff;
    -webkit-transition: -webkit-transform 0.35s;
    transition: transform 0.35s;
    -webkit-transform: translate3d(0,100%,0);
    transform: translate3d(0,100%,0);
}

figure.imgbox h2 {
    float: center;
}

figure.imgbox figcaption > span {
    float: center;
}

figure.imgbox p {
    position: absolute;
    bottom: 8em;
    padding: 2em;
    color: #fff;
    text-transform: none;
    font-size: 90%;
    opacity: 0;
    -webkit-transition: opacity 0.35s;
    transition: opacity 0.35s;
}

figure.imgbox h2,
figure.imgbox figcaption > span {
    -webkit-transition: -webkit-transform 0.35s;
    transition: transform 0.35s;
    -webkit-transform: translate3d(0,200%,0);
    transform: translate3d(0,200%,0);
}

figure.imgbox figcaption > span::before {
    display: inline-block;
    padding: 8px 10px;
    font-family: 'feathericons';
    speak: none;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
}

.icon-eye::before {
    content: '\e000';
}

.icon-paper-clip::before {
    content: '\e001';
}

.icon-heart::before {
    content: '\e024';
}

figure.imgbox h2 {
    display: inline-block;
}

figure.imgbox:hover p {
    opacity: 1;
}

figure.imgbox:hover figcaption,
figure.imgbox:hover h2,
figure.imgbox:hover figcaption > span {
    -webkit-transform: translate3d(0,0,0);
    transform: translate3d(0,0,0);
}

figure.imgbox:hover h2 {
    -webkit-transition-delay: 0.05s;
    transition-delay: 0.05s;
}

figure.imgbox:hover figcaption > span:nth-child(4) {
    -webkit-transition-delay: 0.1s;
    transition-delay: 0.1s;
}

figure.imgbox:hover figcaption > span:nth-child(3) {
    -webkit-transition-delay: 0.15s;
    transition-delay: 0.15s;
}

figure.imgbox:hover figcaption > span:nth-child(2) {
    -webkit-transition-delay: 0.2s;
    transition-delay: 0.2s;
}

可能是网格有问题？

Answer 1

这与以下事实有关:当您将 box-shadow 应用于 figure 元素时，图像会位于它之上并遮挡 盒子阴影。此外，据我所知，阴影不能直接应用于图像。

您可以使用 :before 规则来解决这个问题，或者您可以将图像作为 background-image 应用到 figure并将 box-shadow 也应用于此元素。

:before 的 css，保持你的标记不变，将是这样的:

.imgbox:before {
    content: "";
    height: 100%;
    width: 100%;
    position: absolute;
    box-shadow: inset 0px 0px 10px rgba(0, 0, 0, 1);
    z-index: 2;
}
.imgbox img {
    position:relative;
    z-index:1;
}
