文字


语法:

<linear-gradient> = linear-gradient([ [ <angle> | to <side-or-corner> ] ,]? <color-stop>[, <color-stop>]+)

<side-or-corner> = [left | right] || [top | bottom]

<color-stop> = <color> [ <length> | <percentage> ]?

取值:

下述值用来表示渐变的方向,可以使用角度或者关键字来设置:

  • <angle>:用角度值指定渐变的方向(或角度)。

  • to left:设置渐变为从右到左。相当于: 270deg

  • to right:设置渐变从左到右。相当于: 90deg

  • to top:设置渐变从下到上。相当于: 0deg

  • to bottom:设置渐变从上到下。相当于: 180deg。这是默认值,等同于留空不写。

<color-stop> 用于指定渐变的起止颜色:

  • <color>:指定颜色。

  • <length>:用长度值指定起止色位置。不允许负值

  • <percentage>:用百分比指定起止色位置。

说明:

用线性渐变创建图像。
  • 如果想创建以对角线方式渐变的图像,可以使用 to top left 这样的多关键字方式来实现。

  • 用默认的渐变方向绘制一个最简单的线性渐变

    示例代码:

    linear-gradient.png
    (图一)

    linear-gradient(#fff, #333); linear-gradient(to bottom, #fff, #333); linear-gradient(to top, #333, #fff); linear-gradient(180deg, #fff, #333); linear-gradient(to bottom, #fff 0%, #333 100%);

    以上几句代码都可以实现如(图一)的渐变效果

  1. 使用过时的语法:-webkit-gradient(linear,…)

  2. IE6.0-9.0使用私有滤镜来实现该效果: progid:DXImageTransform.Microsoft.Gradient()
