蒙版/渐变
① -webkit-gradient(<type>, <x1 y1>, <x2 y2> , from(颜色1) ,to(颜色2))
渐变类型type:linear（线性渐变）或者radial（径向渐变）
渐变起点;x1,y1(可以用left，top等表示)
渐变终点:x2,y2(可以用left，bottom等表示)
background: -webkit- gradient(linear, left top, left bottom, #bccfe3, #d2dded);
②最新式的写法:
线性渐变：
-webkit-linear-gradient(渐变起点,颜色1,颜色2);
-webkit-linear-gradient(top,#ace,#f96);
径向渐变：
-webkit-radial-gradient(渐变起点,颜色1,颜色2);
-webkit-radial-gradient(top,#ace,#f96);
③彩虹式渐变(含百分百)
background: -moz-linear-gradient(left, #ace, #f96 5%, #ace, #f96 95%, #ace);
background: -webkit-gradient(linear, left top, right top, from(#ace), color-stop(0.05, #f96), color-stop(0.5, #ace), color-stop(0.95, #f96), to(#ace));
④放射性渐变radial
background: -moz-radial-gradient(#ace, #f96, #1E90FF);
background: -webkit-radial-gradient(#ace, #f96, #1E90FF);
background: -moz-radial-gradient(#ace 5%, #f96 25%, #1E90FF 50%);
background: -webkit-radial-gradient(#ace 5%, #f96 25%, #1E90FF 50%);
background: -moz-radial-gradient(bottom left,circle, #ace, #f96, #1E90FF);
background: -webkit-radial-gradient(bottom left, circle, #ace, #f96, #1E90FF);
⑤制作背景图
⑥线性渐变在IE的应用：
filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0, startColorstr=#1471da, endColorstr=#1C85FB);/*IE<9>*/
-ms-filter: "progid:DXImageTransform.Microsoft.gradient (GradientType=0, startColorstr=#1471da, endColorstr=#1C85FB)";/*IE8+*/
IE依靠滤镜实现渐变。startColorstr表示起点的颜色，endColorstr表示终点颜色。
GradientType表示渐变类型，0为缺省值，表示垂直渐变，1表示水平渐变。
⑦Firefox支持两种类型的CSS渐变
线性的(-moz-linear-gradient)和放射状的(-moz-radial-gradient)。

background: -webkit-radial-gradient(#ace 5%, #f96 25%, #1E90FF 50%);
background: -moz-radial-gradient(bottom left,circle, #ace, #f96, #1E90FF);
background: -webkit-radial-gradient(bottom left, circle, #ace, #f96, #1E90FF);
