CSS3 制作Drop Shadow效果

转自：http://www.w3cplus.com/css3/box-drop-down-shadow-with-css3

在介绍CSS3系列时，我花了一篇很长的篇幅专门介绍了CSS3的box-shadow属性以及其具体的使用等。在此文末尾还介绍了使用box-shadow配合CSS3的伪类中的“:before”和“:after”制作Box Drop Shadow效果的实例。随着CSS3和HTML5的不断发展和壮大，大家在平时中也发现了不少实例或网站都不需要使用图片来进行设计了，直接使用代码来完成。今天我们就在前面的基础上进行深层次的挖掘——使用CSS3的制作不同的Box Drop Shadow效果。 如：

正如前面所言，下面的代码让我们再一次展示了CSS3的强大。今天我们主要使用CSS3的box-shadow配合部分标签和CSS3的伪类中的“:before”和“:after”制作各种不同的Box Drop Shadow效果

制作这些效果比你想象的要简单多，你只需要熟悉CSS3的属性，那么你就可以轻松的不使用任何图形软件开始你的设计。同样的原理，使用CSS3来做设计效果，我们始终少不了的一样东西，那就是HTML Markup。

基本的HTML Markup:

<div class="box"></div>

我们使用CSS3制作Box Drop Shadow效果，最原始的就是需要上面的一个HTML结构。如果你需要制作不同的效果，我们只需要在此基础上加上不同的类名，比如说“box1”、“box2”等，此处我们把上面的结构叫做基类，或者叫模板也行，同时我们给其一个简单的样式。

【注】：下面的所有实例，如果没有进行特殊说明，其HTML结构都是以此代码为例。

基本的CSS Code

.box {width: 300px;min-height: 300px;margin: 30px;display: inline-block;background: #fff;border: 1px solid #ccc;position:relative;}

为了更好介绍本教程的内容，我在此处统一了所有Box的大小，其中所有样式你都可以根据自己需要去修改，唯一一点position:relative;是不能少的。下面我们分别一种一种效果来介绍：

【注】：下面的所有实例，都是在“div.box”样式基础上实现，下面每例其他的代码都以“box1”、“box2”等来区别，如果你需要单独使用每一例，记得加上上面的样式代码。。

效果一：

效果一是制作一个简单的阴影效果，让盒子左上角和右下角有一个小阴影，并添加了少许的内阴影效果，来增强质感。那么一起来看代码吧。

CSS Code

/*=========Box1===========*/.box1{background: -webkit-gradient(linear, 0% 20%, 0% 100%, from(#fff), to(#fff), color-stop(.1,#f3f3f3));background: -webkit-linear-gradient(0% 0%, #fff, #f3f3f3 10%, #fff);background: -moz-linear-gradient(0% 0%, #fff, #f3f3f3 10%, #fff);background: -o-linear-gradient(0% 0%, #fff, #f3f3f3 10%, #fff);/*设置Box的阴影效果*/-webkit-box-shadow: 0px 3px 30px rgba(0, 0, 0, 0.1) inset;-moz-box-shadow: 0px 3px 30px rgba(0, 0, 0, 0.1) inset;box-shadow: 0px 3px 30px rgba(0, 0, 0, 0.1) inset;/*制作右下脚折边效果*/-moz-border-radius: 0 0 6px 0 / 0 0 50px 0;-webkit-border-radius: 0 0 6px 0 / 0 0 50px 0;border-radius: 0 0 6px 0 / 0 0 50px 0;}/*使用:before来制作底部阴影，并对阴影进行旋转的扭曲和位移设置*/.box1:before{content: '';width: 50px;height: 100px;position:absolute;bottom:0; right:0;-webkit-box-shadow: 20px 20px 10px rgba(0, 0, 0, 0.1);-moz-box-shadow: 20px 20px 15px rgba(0, 0, 0, 0.1);box-shadow: 20px 20px 15px rgba(0, 0, 0, 0.1);z-index:-1;-webkit-transform: translate(-35px,-40px)skew(0deg,30deg) rotate(-25deg);-moz-transform: translate(-35px,-40px) skew(0deg,32deg)rotate(-25deg);-o-transform: translate(-35px,-40px) skew(0deg,32deg)rotate(-25deg);transform: translate(-35px,-40px) skew(0deg,32deg)rotate(-25deg);}/*使用:after来制作顶部的阴影，并对阴影进行旋转的扭曲和位移设置*/.box1:after{content: '';width: 100px;height: 100px;top:0; left:0;position:absolute;display: inline-block;z-index:-1;-webkit-box-shadow: -10px -10px 10px rgba(0, 0, 0, 0.2);-moz-box-shadow: -10px -10px 15px rgba(0, 0, 0, 0.2);box-shadow: -10px -10px 15px rgba(0, 0, 0, 0.2);-webkit-transform: rotate(2deg)translate(20px,25px) skew(20deg);-moz-transform: rotate(7deg) translate(20px,25px) skew(20deg);-o-transform: rotate(7deg) translate(20px,25px) skew(20deg);transform: rotate(7deg) translate(20px,25px) skew(20deg);}

效果二：

效果二把盒子右下角的阴影和折角效果都放大了，而且内阴影也进行了调整，取代他的是一个渐变的叠加效果。

/*==========Box2============*/.box2{padding: 0 0 1px 0;background: #f3f3f3;background: -webkit-gradient(linear, 0% 20%, 0% 92%, from(#f3f3f3), to(#fff), color-stop(.1,#f3f3f3));background: -webkit-linear-gradient(0 0 270deg, #f3f3f3, #f3f3f3 10%, #fff);background: -moz-linear-gradient(0 0 270deg, #f3f3f3, #f3f3f3 10%, #fff);background: -o-linear-gradient(0 0 270deg, #f3f3f3, #f3f3f3 10%, #fff);border-top: 1px solid #ccc;border-right: 1px solid #ccc;-webkit-border-radius: 0 0 60px 0 / 0 0 60px 0;-moz-border-radius: 0 0 60px 0 / 0 0 60px 0;border-radius: 0 0 60px 0 / 0 0 60px 0;-webkit-box-shadow: -1px 2px 2px rgba(0, 0, 0, 0.2);-moz-box-shadow: -1px 2px 2px rgba(0, 0, 0, 0.2);box-shadow: -1px 2px 2px rgba(0, 0, 0, 0.2);}.box2:before{content:'';width: 25px;height: 20px;position: absolute;bottom:0;right:0;-webkit-border-radius: 0 0 30px 0;-moz-border-radius: 0 0 30px 0;border-radius: 0 0 30px 0;-webkit-box-shadow: -2px -2px 5px rgba(0, 0, 0, 0.3);-moz-box-shadow: -2px -2px 5px rgba(0, 0, 0, 0.3);box-shadow:-2px -2px 5px rgba(0, 0, 0, 0.3);-webkit-transform:rotate(-20deg) skew(-40deg,-3deg) translate(-13px,-13px);-moz-transform:rotate(-20deg) skew(-40deg,-3deg) translate(-13px,-13px);-o-transform:rotate(-20deg) skew(-40deg,-3deg) translate(-13px,-13px);transform: rotate(-20deg) skew(-40deg,-3deg) translate(-13px,-13px);}/*这里，我们做出的褶皱阴影*/.box2:after{content: '';z-index: -1;width: 100px;height: 100px;position:absolute;bottom:0;right:0;background: rgba(0, 0, 0, 0.2);display: inline-block;-webkit-box-shadow: 20px 20px 8px rgba(0, 0, 0, 0.2);-moz-box-shadow: 20px 20px 18px rgba(0, 0, 0, 0.2);box-shadow: 20px 20px 8px rgba()0,0,0,0.2;-webkit-transform: rotate(0deg) translate(-45px,-20px) skew(20deg);-moz-transform: rotate(0deg) translate(-45px,-20px) skew(20deg);-o-transform: rotate(0deg) translate(-45px,-20px) skew(20deg);transform: rotate(0deg) translate(-45px,-20px) skew(20deg);   }

效果三：

效果三是使用CSS3来实现一个模拟小皱纹的效果，大家可以仔细留意Box的顶部和底部的效果。

CSS CODE

/*==========Box3=========*/.box3{padding: 5px 0 ;background: -webkit-gradient(linear, 0% 20%, 0% 92%, from(#fff), to(#f3f3f3), color-stop(.1,#fff));background: -webkit-linear-gradient(0 0 270deg, #f3f3f3, #f3f3f3 10%, #fff);background: -moz-linear-gradient(0 0 270deg, #f3f3f3, #f3f3f3 10%, #fff);background: -o-linear-gradient(0 0 270deg, #f3f3f3, #f3f3f3 10%, #fff);-webkit-border-radius: 60px / 5px;-moz-border-radius: 60px / 5px;border-radius:60px / 5px;-webkit-box-shadow: 0px 0px 35px rgba(0, 0, 0, 0.1) inset;-moz-box-shadow: 0px 0px 35px rgba(0, 0, 0, 0.1) inset;box-shadow: 0px 0px 35px rgba(0, 0, 0, 0.1) inset;}.box3:before{content: '';width: 50px;height: 50px;top:0; right:0;position:absolute;display: inline-block;z-index:-1;-webkit-box-shadow: 10px -10px 8px rgba(0, 0, 0, 0.2);-moz-box-shadow: 10px -10px 8px rgba(0, 0, 0, 0.2);box-shadow: 10px -10px 8px rgba(0, 0, 0, 0.2);-webkit-transform: rotate(2deg) translate(-14px,20px) skew(-20deg);-moz-transform: rotate(2deg) translate(-14px,20px) skew(-20deg);-o-transform: rotate(2deg) translate(-14px,20px) skew(-20deg);transform: rotate(2deg) translate(-14px,20px) skew(-20deg);}.box3:after{content: '';width: 100px;height: 100px;top:0; left:0;position:absolute;z-index:-1;display: inline-block;-webkit-box-shadow: -10px -10px 10px rgba(0, 0, 0, 0.2);-moz-box-shadow: -10px -10px 10px rgba(0, 0, 0, 0.2);box-shadow: -10px -10px 10px rgba(0, 0, 0, 0.2);-webkit-transform: rotate(2deg) translate(20px,25px) skew(20deg);-moz-transform: rotate(2deg) translate(20px,25px) skew(20deg);-o-transform: rotate(2deg) translate(20px,25px) skew(20deg);transform: rotate(2deg) translate(20px,25px) skew(20deg);}

效果四：

效果四是在盒子四个角都有一个阴影，这样一来只单独配合“:before”和“:after”就无法实现了，从前面的实例大家都应该非常清楚，上面每个实例的阴影都是有由他们各自的“:before”和“:after”实现，这样一来要制作四个角的阴影我们就需要使用另外两个空的<div>来补做阴影的效果。

HTML Markup

<div class="box box4"><div class="shBl"><!-- 左下角阴影 --></div><div class="shBr"><!-- 右下角阴影 --></div></div>

CSS CODE

/*============Box4==============*/.box4{padding: 5px 0 ;background: #fff;background: -webkit-gradient(linear, 0% 20%, 0% 100%, from(#fff), to(#fff), color-stop(.2, #f2f2f2));background: -webkit-linear-gradient(0% 0% 360deg, #fff, #f2f2f2 20%, #fff );background: -moz-linear-gradient(0% 0% 360deg, #fff, #f2f2f2 20%, #fff );background: -o-linear-gradient(0% 0% 360deg, #fff, #f2f2f2 20%, #fff );-webkit-box-shadow: 0px 0px 10px rgba(0, 0, 0, 0.3);-moz-box-shadow: 0px 0px 10px rgba(0, 0, 0, 0.3);box-shadow: 0px 0px 10px rgba(0, 0, 0, 0.3);}.box4:before{content: '';width: 50px;height: 50px;top:0; right:0;position:absolute;z-index: -1;-webkit-box-shadow: 10px -10px 8px rgba(0, 0, 0, 0.2);-moz-box-shadow: 10px -10px 8px rgba(0, 0, 0, 0.2);box-shadow: 10px -10px 8px rgba(0, 0, 0, 0.2);-webkit-transform: rotate(2deg) translate(-14px,20px) skew(-20deg);-moz-transform: rotate(2deg) translate(-14px,20px) skew(-20deg);-o-transform: rotate(2deg) translate(-14px,20px) skew(-20deg); transform: rotate(2deg) translate(-14px,20px) skew(-20deg);}.box4:after{content: '';width: 50px;height: 50px;top:0; left:0;position:absolute;z-index:-1;display: inline-block;-webkit-box-shadow: -10px -10px 10px rgba(0, 0, 0, 0.2);-moz-box-shadow: -10px -10px 10px rgba(0, 0, 0, 0.2);box-shadow: -10px -10px 10px rgba(0, 0, 0, 0.2);-webkit-transform: rotate(2deg) translate(12px,25px) skew(20deg);-moz-transform: rotate(2deg) translate(12px,25px) skew(20deg);-o-transform: rotate(2deg) translate(12px,25px) skew(20deg);transform: rotate(2deg) translate(12px,25px) skew(20deg);}/*盒子右下角阴影效果*/.box4 .shBr{width: 100px;height: 100px;bottom:0; right:0;position:absolute;z-index: -1;-webkit-box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.2);-moz-box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.2);box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.2);-webkit-transform: rotate(0deg) translate(-20px,-15px) skew(20deg);-moz-transform: rotate(0deg) translate(-20px,-15px) skew(20deg);-o-transform: rotate(0deg) translate(-20px,-15px) skew(20deg);transform: rotate(0deg) translate(-20px,-15px) skew(20deg);   }/*盒子左下角阴影效果*/.box4 .shBl{width: 100px;height: 100px;bottom:0; left:0;position:absolute;z-index: -1;-webkit-box-shadow: -10px 10px 10px rgba(0, 0, 0, 0.2);-moz-box-shadow: -10px 10px 10px rgba(0, 0, 0, 0.2);box-shadow: -10px 10px 10px rgba(0, 0, 0, 0.2);-webkit-transform: rotate(0deg) translate(20px,-15px) skew(-20deg);-moz-transform: rotate(0deg) translate(20px,-15px) skew(-20deg);-o-transform: rotate(0deg) translate(20px,-15px) skew(-20deg);transform: rotate(0deg) translate(20px,-15px) skew(-20deg);   }

效果五

这个效果制作底下两个折角效果，带上阴影更如纸张的样子了。此例也需要借助两个<div>来辅助，才能有效果。

效果六：

效果六是另一种皱纹的效果。这种效果和效果二极其相似，只是我们在box左上角和右上角加了一点特效。

上面我主要给大家展示了十五种用CSS3制作的各种不同的Box Drop Shadow效果。这是一种纯CSS制作的效果，很久以前需要使用纯CSS来实现上面的效果是一种不可想象的事情，那么现在实现了，而且是轻松的实现了。当然，有时你会感觉自己去创作会有点烦，那么你也可以使用wordpressthemeshock.com提供的在线制作Drop Shadow效果的工具。

今天主要和大家一起见证了使用纯CSS3来制作不同效果的Box Drop Shadow效果。从上面的代码中，我们不难发现，使用CSS3制作上面的效果，主要使用了其：Border-radius、box-shadow、transform、RGBA以及他的伪类“:before”和“:after”。总得来说，只要你有想象力，创造力，在配上你对CSS3各种属性的灵活度，你就能用他写出你想要的效果。那么今天就到此，有关于Box Drop Shadow的介绍就完了，如果你对上面的效果感兴趣，那就快动手来一次吧，或者直接点击下面的Demo。
