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);

![20170426105958781][]

 background: -webkit-radial-gradient(\#ace 5%, \#f96 25%, \#1E90FF 50%);

background: -moz-radial-gradient(bottom left,circle, \#ace, \#f96, \#1E90FF);

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)。
