使用css3 属性如何丰富图片样式(圆角 阴影 渐变)

.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
在这个例子中我们为图片包装添加transition属性，鼠标滑过的时候，他会从圆角变为圆形。然后我们使用多个box-shadow实现发光效果。
 
css：

复制代码
.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;
}

高光效果
高光的效果是通过为元素添加 :after 伪类实现的。
 
css：

复制代码
.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%);
}

倒影效果
在这个例子中，我们将高光效果移到底部就实现倒影效果。
 
css：

复制代码
.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;
}
