-
<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。
示例:
-
-
div {
width: 200px;
height: 100px;
margin: 10px 5px;
border: 1px solid #ddd000;
}
#LinearStartToEnd {
float:left;
background: linear-gradient(#ff0000, #00ff00);
}
#LinearPercentage {
float:left;
background: linear-gradient(#0000ff, #ff0000 52%, #00ff00);
}
#LinearAnglePercentage {
float:left;
background: linear-gradient(90deg, #ff0000 20%, #00ff00 50%, #000000 80%);
}
#LinearAngle {
float:left;
background: linear-gradient(30deg, #ffff00 30%, #ff0000, #00ff00);
}
#LinearTopRight {
float:left;
background: linear-gradient(to right top, #00ff00, #ff0000 50%, #0000ff);
}
2.径向渐变:radial-gradient -
语法:
<position> = [ <length>①
| <percentage>① | left | center① | right ]? [ <length>②
| <percentage>② | top | center② | bottom ]?
<shape> = circle | ellipse
<size> = <extent-keyword>|[<circle-size>||<ellipse-size>]
<extent-keyword> = closest-side | closest-corner | farthest-side | farthest-corner
<circle-size> = <length>
<ellipse-size> = [ <length>| <percentage> ]{2}
<shape-size> = <length>| <percentage>
-
<radial-gradient> = radial-gradient([ [ <shape>|| <size> ]
[ at <position> ]? , | at <position> ,
]?<color-start>[[ , <color-end>]]+)

示例:
#RadialCenterCircle {
float:left;
background: radial-gradient(circle at center, #ff0000, #ffff00, #00ffff);
}
#RadialClosestSide {
float:left;
background: radial-gradient(circle closest-side, #ff0000, #00ff00, #ffff00);
}
#RadialFarthestSide {
float:left;
background: radial-gradient(farthest-side, #ff0000 20%, #ffff00 60%, #00ff00 80%);
}
#RadialRightTop {
float:left;
background: radial-gradient(at right top, #ff0000, #ffff00, #00ff00);
}
#RadialRadiusCenter {
float:left;
background: radial-gradient(farthest-side at top right, #ff0000, #ffff00, #01fefe);
}
#RadialGroup {
float:left;
background:
radial-gradient(farthest-side at top right, #ff0000, #ffff00, #009f00, transparent),
radial-gradient(60px at top left, #ff0000, #ffff00, #00ff0e);
}

3.重复的线性渐变:repeating-linear-gradient
语法和参数类似线性渐变,这里不在赘述。详情请参考CSS手册。
-
示例:
-
#RepeatingLinearPercentage{
float:left;
background: repeating-linear-gradient(#ff0000, #00ff00 10%, #000000 15%);
}
#RepeatingLinearRight {
float:left;
background: repeating-linear-gradient(to right, #ff0000, #00ff00 10%, #000000 15%);
}
#RepeatingLinearAngle {
float:left;
background: repeating-linear-gradient(45deg, #ff0000, #00ff00 10%, #0000ff 15%);
}
#RepeatingLinearBottomLeft {
float:left;
background: repeating-linear-gradient(to bottom left, #00ffff, #ff0000 10%, #00ff00 15%);
}
3.重复的径向渐变:repeating-radial-gradient
-
语法和参数类似径向渐变,这里不在赘述。详情请参考CSS手册。

示例:
#RepeatingRadialCircle {
float:left;
background: repeating-radial-gradient(circle, #ff0000 0, #00ff00 10%, #0000ff 15%);
}
#RepeatingRadialTopLeft {
float:left;
background: repeating-radial-gradient(at top left, #ff0000, #00ff00 10%, #0de0f0 15%, #ffff00 20%, #000000 25%);
}
#RepeatingRadialClosestCorner {
float:left;
background: repeating-radial-gradient(circle closest-corner at 20px 50px, #00ff00, #ff0000 10%, #00ffff 20%, #ffff00 30%, #ff00ff 40%);
}
