文字

语法：

<repeating-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：

用重复的线性渐变创建图像。

  • repeating-linear-gradient()的语法与linear-gradient()相同。

  • 示例代码：

    repeating-linear-gradient.png
    （图一）

    repeating-linear-gradient(#f00, #ff0 10%, #f00 15%); repeating-linear-gradient(to bottom, #f00, #ff0 10%, #f00 15%); repeating-linear-gradient(180deg, #f00, #ff0 10%, #f00 15%); repeating-linear-gradient(to top, #f00, #ff0 10%, #f00 15%);

    以上几句代码都可以实现如（图一）的渐变效果

  • 其实可以使用 linear-gradient() 做出 repeating-linear-gradient() 的效果

    暴力实现上述（图一）的效果：

    repeating-linear-linear-gradient(#f00, #ff0 10%, #f00 15%, #ff0 25%, #f00 30%, #ff0 40%, #f00 45%, #ff0 55%, #f00 60%, #ff0 70%, #f00 75%, #ff0 85%, #f00 90%, #ff0);

    以上几句代码都可以实现如（图一）的渐变效果

    利用 background-size 实现上述（图一）的效果：

    background: linear-gradient(#f00, #ff0 67%, #f00); background-size: 100% 15%;

    使用 background-size 约束渐变图像的大小，然后通过 background-repeat 来纵向平铺

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