当在图像元素上直接使用CSS3内阴影或者圆角边框时，浏览器对于CSS样式的渲染并不完美。但是，如果图像作为背景图像使用时，你可以为它添加任何样式，而且可以实现完美的渲染。Darcy Clarke和我一起编写了一个如何使用jQuery来动态创建完美圆角边框的快速教程。今天我要重启这个话题，向你展示使用CSS的背景图像技巧我们还可以做多少事情。我将向你展示如何使用盒阴影、圆角边框和转换来创建不同的图像样式。

查看演示**](http://webdesignerwall.com/demo/css3-image-styles/)
**问题（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
查看演示，你会发现第一排的图像应用了圆角边框和内阴影。Firefox在图片元素上支持圆角边框，但是不支持内阴影的渲染。Chrome和Safari完全不支持圆角边框和内阴影的渲染。
**解决方案**
要使用圆角边框和内阴影，解决方案是把所需的图像设置为背景图像。
**动态的方式**
要采用动态的方式实现，你可以使用jQuery来将每一个图像元素动态的包装为背景图像。如下的jQuery代码使用span标签来包装所有的图像，并且将图像应用为背景图像（jQuery代码来自Darcy Clarke）。

*输出*
上面的代码将输入如下的HTML代码：

**圆形图像（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
现在图片已经被应用为背景图像，你几乎可以为它添加任何样式。如下是一个用圆角边框创建的简单圆形图像。如果你还不熟悉CSS3，请阅读我对CSS3的[基础教程](http://webdesignerwall.com/tutorials/the-basics-of-css3)。
**CSS**
~~~
.circle .image-wrap {
-webkit-border-radius: 50em;
-moz-border-radius: 50em;
border-radius: 50em;
}
~~~
**卡片风格（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
如下是一个用多内阴影值创建的卡片图像样式。
**CSS**
~~~
.card .image-wrap {
-webkit-box-shadow: inset 0 0 1px rgba(0,0,0,.8), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -1px 0 rgba(0,0,0,.4);
-moz-box-shadow: inset 0 0 1px rgba(0,0,0,.8), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -1px 0 rgba(0,0,0,.4);
box-shadow: inset 0 0 1px rgba(0,0,0,.8), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -1px 0 rgba(0,0,0,.4);
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
~~~
**浮雕风格（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
做一些调整，我可以将卡片样式变成浮雕样式。
**CSS**
~~~
.embossed .image-wrap {
-webkit-box-shadow: inset 0 0 2px rgba(0,0,0,.8), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -7px 0 rgba(0,0,0,.6), inset 0 -9px 0 rgba(255,255,255,.3);
-moz-box-shadow: inset 0 0 2px rgba(0,0,0,.8), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -7px 0 rgba(0,0,0,.6), inset 0 -9px 0 rgba(255,255,255,.3);
box-shadow: inset 0 0 2px rgba(0,0,0,.8), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -7px 0 rgba(0,0,0,.6), inset 0 -9px 0 rgba(255,255,255,.3);
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
~~~
**软浮雕风格（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
这几乎和浮雕样式相同，我只加了1个像素的模糊。
**CSS**
~~~
.embossed .image-wrap {
-webkit-box-shadow: inset 0 0 2px rgba(0,0,0,.8), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -7px 0 rgba(0,0,0,.6), inset 0 -9px 0 rgba(255,255,255,.3);
-moz-box-shadow: inset 0 0 2px rgba(0,0,0,.8), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -7px 0 rgba(0,0,0,.6), inset 0 -9px 0 rgba(255,255,255,.3);
box-shadow: inset 0 0 2px rgba(0,0,0,.8), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -7px 0 rgba(0,0,0,.6), inset 0 -9px 0 rgba(255,255,255,.3);
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
~~~
**剪贴画风格（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
再次通过对内阴影的调整，我可以让它看起来像一个剪贴画效果。
**CSS**
~~~
.cut-out .image-wrap {
-webkit-box-shadow: 0 1px 0 rgba(255,255,255,.2), inset 0 4px 5px rgba(0,0,0,.6), inset 0 1px 0 rgba(0,0,0,.6);
-moz-box-shadow: 0 1px 0 rgba(255,255,255,.2), inset 0 4px 5px rgba(0,0,0,.6), inset 0 1px 0 rgba(0,0,0,.6);
box-shadow: 0 1px 0 rgba(255,255,255,.2), inset 0 4px 5px rgba(0,0,0,.6), inset 0 1px 0 rgba(0,0,0,.6);
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
~~~
**变形和发光（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
在这个例子汇总，我为图像的包装元素添加了transition。当鼠标滑过，它会从圆角边框变为圆形并添加发光的效果。发光效果采用多盒阴影值实现。
**CSS**
~~~
.morphing-glowing .image-wrap {
-webkit-transition: 1s;
-moz-transition: 1s;
transition: 1s;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
.morphing-glowing .image-wrap:hover {
-webkit-box-shadow: 0 0 20px rgba(255,255,255,.6), inset 0 0 20px rgba(255,255,255,1);
-moz-box-shadow: 0 0 20px rgba(255,255,255,.6), inset 0 0 20px rgba(255,255,255,1);
box-shadow: 0 0 20px rgba(255,255,255,.6), inset 0 0 20px rgba(255,255,255,1);
-webkit-border-radius: 60em;
-moz-border-radius: 60em;
border-radius: 60em;
}
~~~
**光泽覆盖（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
我们采用:after伪类元素实现如下的光泽渐变覆盖效果。
**CSS**
~~~
.glossy .image-wrap {
-webkit-box-shadow: inset 0 -1px 0 rgba(0,0,0,.5);
-moz-box-shadow: inset 0 -1px 0 rgba(0,0,0,.5);
box-shadow: inset 0 -1px 0 rgba(0,0,0,.5);
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
.glossy .image-wrap:after {
position: absolute;
content: ' ';
width: 100%;
height: 50%;
top: 0;
left: 0;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
background: -moz-linear-gradient(top, rgba(255,255,255,0.7) 0%, rgba(255,255,255,.1) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(255,255,255,0.7)), color-stop(100%,rgba(255,255,255,.1)));
background: linear-gradient(top, rgba(255,255,255,0.7) 0%,rgba(255,255,255,.1) 100%);
}
~~~
**投影（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
在这个例子中，我将覆盖渐变换到底部来创建投影效果。
**CSS**
~~~
.reflection .image-wrap:after {
position: absolute;
content: ' ';
width: 100%;
height: 30px;
bottom: -31px;
left: 0;
-webkit-border-top-left-radius: 20px;
-webkit-border-top-right-radius: 20px;
-moz-border-radius-topleft: 20px;
-moz-border-radius-topright: 20px;
border-top-left-radius: 20px;
border-top-right-radius: 20px;
background: -moz-linear-gradient(top, rgba(0,0,0,.3) 0%, rgba(255,255,255,0) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(0,0,0,.3)), color-stop(100%,rgba(255,255,255,0)));
background: linear-gradient(top, rgba(0,0,0,.3) 0%,rgba(255,255,255,0) 100%);
}
.reflection .image-wrap:hover {
position: relative;
top: -8px;
}
~~~
**光泽和投影（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
在这个示例中，我将:before和:after合并，用来创建带投影效果的光泽头像。
**CSS**
~~~
.glossy-reflection .image-wrap {
-webkit-box-shadow: inset 0 -1px 0 rgba(0,0,0,.5), inset 0 1px 0 rgba(255,255,255,.6);
-moz-box-shadow: inset 0 -1px 0 rgba(0,0,0,.5), inset 0 1px 0 rgba(255,255,255,.6);
box-shadow: inset 0 -1px 0 rgba(0,0,0,.5), inset 0 1px 0 rgba(255,255,255,.6);
-webkit-transition: 1s;
-moz-transition: 1s;
transition: 1s;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
.glossy-reflection .image-wrap:before {
position: absolute;
content: ' ';
width: 100%;
height: 50%;
top: 0;
left: 0;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
background: -moz-linear-gradient(top, rgba(255,255,255,0.7) 0%, rgba(255,255,255,.1) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(255,255,255,0.7)), color-stop(100%,rgba(255,255,255,.1)));
background: linear-gradient(top, rgba(255,255,255,0.7) 0%,rgba(255,255,255,.1) 100%);
}
.glossy-reflection .image-wrap:after {
position: absolute;
content: ' ';
width: 100%;
height: 30px;
bottom: -31px;
left: 0;
-webkit-border-top-left-radius: 20px;
-webkit-border-top-right-radius: 20px;
-moz-border-radius-topleft: 20px;
-moz-border-radius-topright: 20px;
border-top-left-radius: 20px;
border-top-right-radius: 20px;
background: -moz-linear-gradient(top, rgba(230,230,230,.3) 0%, rgba(230,230,230,0) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(230,230,230,.3)), color-stop(100%,rgba(230,230,230,0)));
background: linear-gradient(top, rgba(230,230,230,.3) 0%,rgba(230,230,230,0) 100%);
}
~~~
**磁带风格（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
这里使用:after来在图像的上部创建磁带式的渐变。
**CSS**
~~~
.tape .image-wrap {
-webkit-box-shadow: inset 0 0 2px rgba(0,0,0,.7), inset 0 2px 0 rgba(255,255,255,.3), inset 0 -1px 0 rgba(0,0,0,.5), 0 1px 3px rgba(0,0,0,.4);
-moz-box-shadow: inset 0 0 2px rgba(0,0,0,.7), inset 0 2px 0 rgba(255,255,255,.3), inset 0 -1px 0 rgba(0,0,0,.5), 0 1px 3px rgba(0,0,0,.4);
box-shadow: inset 0 0 2px rgba(0,0,0,.7), inset 0 2px 0 rgba(255,255,255,.3), inset 0 -1px 0 rgba(0,0,0,.5), 0 1px 3px rgba(0,0,0,.4);
}
.tape .image-wrap:after {
position: absolute;
content: ' ';
width: 60px;
height: 25px;
top: -10px;
left: 50%;
margin-left: -30px;
border: solid 1px rgba(137,130,48,.2);
background: -moz-linear-gradient(top, rgba(254,243,127,.6) 0%, rgba(240,224,54,.6) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(254,243,127,.6)), color-stop(100%,rgba(240,224,54,.6)));
background: linear-gradient(top, rgba(254,243,127,.6) 0%,rgba(240,224,54,.6) 100%);
-webkit-box-shadow: inset 0 1px 0 rgba(255,255,255,.3), 0 1px 0 rgba(0,0,0,.2);
}
~~~
**变形和上色（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
在如下的示例里，我使用:after元素在鼠标滑过时创建径向渐变。
**CSS**
~~~
.morphing-tinting .image-wrap {
position: relative;
-webkit-transition: 1s;
-moz-transition: 1s;
transition: 1s;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
.morphing-tinting .image-wrap:hover {
-webkit-border-radius: 30em;
-moz-border-radius: 30em;
border-radius: 30em;
}
.morphing-tinting .image-wrap:after {
position: absolute;
content: ' ';
width: 100%;
height: 100%;
top: 0;
left: 0;
-webkit-transition: 1s;
-moz-transition: 1s;
transition: 1s;
-webkit-border-radius: 30em;
-moz-border-radius: 30em;
border-radius: 30em;
}
.morphing-tinting .image-wrap:hover:after {
background: -webkit-gradient(radial, 50% 50%, 40, 50% 50%, 80, from(rgba(0,0,0,0)), to(rgba(0,0,0,1)));
background: -moz-radial-gradient(50% 50%, circle, rgba(0,0,0,0) 40px, rgba(0,0,0,1) 80px);
}
~~~
**羽毛边圈（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
径向渐变还可以作为遮罩使用来创建圆形的羽毛效果，如下所示。
**CSS**
~~~
.feather .image-wrap {
position: relative;
-webkit-border-radius: 30em;
-moz-border-radius: 30em;
border-radius: 30em;
}
.feather .image-wrap:after {
position: absolute;
content: ' ';
width: 100%;
height: 100%;
top: 0;
left: 0;
background: -webkit-gradient(radial, 50% 50%, 50, 50% 50%, 70, from(rgba(255,255,255,0)), to(rgba(255,255,255,1)));
background: -moz-radial-gradient(50% 50%, circle, rgba(255,255,255,0) 50px, rgba(255,255,255,1) 70px);
}
~~~
**浏览器支持**
这个技巧几乎可以工作在任何支持圆角边框、盒阴影、:after和:before的浏览器上（例如Chrome、Firefox和Safari）。不支持的浏览器会显示没有任何样式的图像。
**使用你的创造力**
正如你看到的一样，使用:before和:after伪元素你几乎可以创建任何图像风格。如果你有更富有创造力的图像风格，请在评论中分享。

**光泽和投影（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
在这个示例中，我将:before和:after合并，用来创建带投影效果的光泽头像。
**CSS**

**磁带风格（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
这里使用:after来在图像的上部创建磁带式的渐变。
**CSS**
~~~
.tape .image-wrap {
-webkit-box-shadow: inset 0 0 2px rgba(0,0,0,.7), inset 0 2px 0 rgba(255,255,255,.3), inset 0 -1px 0 rgba(0,0,0,.5), 0 1px 3px rgba(0,0,0,.4);
-moz-box-shadow: inset 0 0 2px rgba(0,0,0,.7), inset 0 2px 0 rgba(255,255,255,.3), inset 0 -1px 0 rgba(0,0,0,.5), 0 1px 3px rgba(0,0,0,.4);
box-shadow: inset 0 0 2px rgba(0,0,0,.7), inset 0 2px 0 rgba(255,255,255,.3), inset 0 -1px 0 rgba(0,0,0,.5), 0 1px 3px rgba(0,0,0,.4);
}
.tape .image-wrap:after {
position: absolute;
content: ' ';
width: 60px;
height: 25px;
top: -10px;
left: 50%;
margin-left: -30px;
border: solid 1px rgba(137,130,48,.2);
background: -moz-linear-gradient(top, rgba(254,243,127,.6) 0%, rgba(240,224,54,.6) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(254,243,127,.6)), color-stop(100%,rgba(240,224,54,.6)));
background: linear-gradient(top, rgba(254,243,127,.6) 0%,rgba(240,224,54,.6) 100%);
-webkit-box-shadow: inset 0 1px 0 rgba(255,255,255,.3), 0 1px 0 rgba(0,0,0,.2);
}

**变形和上色（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
在如下的示例里，我使用:after元素在鼠标滑过时创建径向渐变。
**CSS**
~~~
.morphing-tinting .image-wrap {
position: relative;
-webkit-transition: 1s;
-moz-transition: 1s;
transition: 1s;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
.morphing-tinting .image-wrap:hover {
-webkit-border-radius: 30em;
-moz-border-radius: 30em;
border-radius: 30em;
}
.morphing-tinting .image-wrap:after {
position: absolute;
content: ' ';
width: 100%;
height: 100%;
top: 0;
left: 0;
-webkit-transition: 1s;
-moz-transition: 1s;
transition: 1s;
-webkit-border-radius: 30em;
-moz-border-radius: 30em;
border-radius: 30em;
}
.morphing-tinting .image-wrap:hover:after {
background: -webkit-gradient(radial, 50% 50%, 40, 50% 50%, 80, from(rgba(0,0,0,0)), to(rgba(0,0,0,1)));
background: -moz-radial-gradient(50% 50%, circle, rgba(0,0,0,0) 40px, rgba(0,0,0,1) 80px);
}
~~~
**羽毛边圈（见[演示](http://webdesignerwall.com/demo/css3-image-styles/)）**
径向渐变还可以作为遮罩使用来创建圆形的羽毛效果，如下所示。
**CSS**
~~~
.feather .image-wrap {
position: relative;
-webkit-border-radius: 30em;
-moz-border-radius: 30em;
border-radius: 30em;
}
.feather .image-wrap:after {
position: absolute;
content: ' ';
width: 100%;
height: 100%;
top: 0;
left: 0;
background: -webkit-gradient(radial, 50% 50%, 50, 50% 50%, 70, from(rgba(255,255,255,0)), to(rgba(255,255,255,1)));
background: -moz-radial-gradient(50% 50%, circle, rgba(255,255,255,0) 50px, rgba(255,255,255,1) 70px);
}

**浏览器支持**
这个技巧几乎可以工作在任何支持圆角边框、盒阴影、:after和:before的浏览器上（例如Chrome、Firefox和Safari）。不支持的浏览器会显示没有任何样式的图像。
**使用你的创造力**
正如你看到的一样，使用:before和:after伪元素你几乎可以创建任何图像风格。如果你有更富有创造力的图像风格，请在评论中分享。
