从上到下的线性渐变：
#grad {
background: -webkit-linear-gradient(red, blue); /* Safari 5.1 - 6.0 */
background: -o-linear-gradient(red, blue); /* Opera 11.1 - 12.0 */
background: -moz-linear-gradient(red, blue); /* Firefox 3.6 - 15 */
background: linear-gradient(red, blue); /* 标准的语法 */
}

从左到右的线性渐变：
#grad {
background: -webkit-linear-gradient(left, red , blue); /* Safari 5.1 - 6.0 */
background: -o-linear-gradient(right, red, blue); /* Opera 11.1 - 12.0 */
background: -moz-linear-gradient(right, red, blue); /* Firefox 3.6 - 15 */
background: linear-gradient(to right, red , blue); /* 标准的语法 */
}
