渐变分为4类

1：线性渐变（Linear Gradients）- 向下/向上/向左/向右/对角方向

2：径向渐变（Radial Gradients）- 由它们的中心定义

3：对角渐变

4：角度渐变

以下是我写的代码

div{float: left;width: 100px;height:100px;}

.odiv1{

background:-moz-linear-gradient(red,blue);

background:-webkit-linear-gradient(red,blue);

background:-ms-linear-gradient(red,blue);

background:-o-linear-gradient(red,blue);

background:linear-gradient(red,blue);/*线性渐变默认情况下是从上到下*/

}

.odiv2{

background:-moz-radial-gradient(red,blue);

background:-webkit-radial-gradient(red,blue);

background:-ms-radial-gradient(red,blue);

background:-o-radial-gradient(red,blue);

background: radial-gradient(red,blue);/*径向渐变*/

}

.odiv3{/* 标准的语法（必须放在最后） */

background:-webkit-linear-gradient(right,red,blue);

background:-moz-linear-gradient(right,red,blue) ;

background:-ms-linear-gradient(right,red,blue);

background:-o-linear-gradient(right,red,blue);

background: linear-gradient(to right,red,blue);/*从右向左渐变*/

}

.odiv4{/*对角渐变左上角開始（到右下角）的线性渐变*/

background: -webkit-linear-gradient(left top,red,blue);

background:-moz-linear-gradient(bottom right,red,blue);

background: -ms-linear-gradient(bottom right,red,blue);

background: -o-linear-gradient(bottom right,red,blue);

background:linear-gradient(to bottom right,red,blue);

}

.odiv5{/*以60度进行的渐变*/

background:-webkit-linear-gradient(60deg,red,blue);

background:-moz-linear-gradient(60deg,red,blue) ;

background:-ms-linear-gradient(60deg,red,blue);

background:-o-linear-gradient(60deg,red,blue);

background:linear-gradient(60deg,red,blue);

}

<div class="odiv1"></div>

<div class="odiv2"></div>

<div class="odiv3"></div>

<div class="odiv4"></div>

<div class="odiv5"></div>

高手勿喷啊！
