CSS linear-gradient() Function

<CSS函数参考

下面的例子表明,从顶端开始,线性渐变。 它开始红,过渡到黄色,再到蓝色:

#grad {
    background: -webkit-linear-gradient(red,yellow,blue); /* Safari 5.1-6.0 */
    background: -o-linear-gradient(red,yellow,blue); /* Opera 11.1-12.0 */
    background: -moz-linear-gradient(red,yellow,blue); /* Firefox 3.6-15 */
    background: linear-gradient(red,yellow,blue); /* Standard syntax */
}

定义和用法

linear-gradient()函数创建一个"image"代表颜色的线性渐变。

要创建必须限定至少两个色标线性渐变。 色标要渲染之间平滑过渡的颜色。 您还可以设置一个起点和一个方向(or an angle)的渐变效果一起。

线性渐变的例子:

版: CSS3

浏览器支持

在表中的数字指定完全支持功能的一个浏览器的版本。

其次通过数字-webkit-,-moz-,或-O-指定用一个前缀工作的第一个版本。

12.1
11.1 -O-

CSS语法

background: linear-gradient( direction , color-stop1 , color-stop2, ... );
描述
direction 限定起点和一个方向(or an angle)与梯度效应沿。
color-stop1, color-stop2,... 色标要渲染之间平滑过渡的颜色。 这个值由一个颜色值,后跟一个可选停止位置(a percentage between 0% and 100% or a length along the gradient axis)
