css3背景渐变色代码

从上到下

#grad {
  background: -webkit-linear-gradient(red, blue);
  background: -o-linear-gradient(red, blue);
  background: -moz-linear-gradient(red, blue);
  background: linear-gradient(red, blue);
}

从左到右

#grad {
  background: -webkit-linear-gradient(left, red , blue);
  background: -o-linear-gradient(right, red, blue);
  background: -moz-linear-gradient(right, red, blue);
  background: linear-gradient(to right, red , blue);
}

从左上到右下

#grad {
  background: -webkit-linear-gradient(left top, red , blue);
  background: -o-linear-gradient(bottom right, red, blue);
  background: -moz-linear-gradient(bottom right, red, blue);
  background: linear-gradient(to bottom right, red , blue);
}

使用角度

#grad {
  background: -webkit-linear-gradient(180deg, red, blue);
  background: -o-linear-gradient(180deg, red, blue);
  background: -moz-linear-gradient(180deg, red, blue);
  background: linear-gradient(180deg, red, blue);
}

多种颜色节点

#grad {
  background: -webkit-linear-gradient(left,red,orange,yellow,green,blue,indigo,violet);
 
  background: -o-linear-gradient(left,red,orange,yellow,green,blue,indigo,violet);
 
  background: -moz-linear-gradient(left,red,orange,yellow,green,blue,indigo,violet);
 
  background: linear-gradient(to right, red,orange,yellow,green,blue,indigo,violet); 
}

使用透明度

#grad {
  background: -webkit-linear-gradient(left,rgba(255,0,0,0),rgba(255,0,0,1));
  background: -o-linear-gradient(right,rgba(255,0,0,0),rgba(255,0,0,1));
  background: -moz-linear-gradient(right,rgba(255,0,0,0),rgba(255,0,0,1));
  background: linear-gradient(to right, rgba(255,0,0,0), rgba(255,0,0,1));
}

径向渐变

#grad {
  background: -webkit-radial-gradient(red, green, blue);
  background: -o-radial-gradient(red, green, blue);
  background: -moz-radial-gradient(red, green, blue);
  background: radial-gradient(red, green, blue);
}

形状为圆形的径向渐变

#grad {
  background: -webkit-radial-gradient(circle, red, yellow, green);
  background: -o-radial-gradient(circle, red, yellow, green);
  background: -moz-radial-gradient(circle, red, yellow, green);
  background: radial-gradient(circle, red, yellow, green);
}

颜色不均匀的径向渐变

#grad {
  background: -webkit-radial-gradient(red 5%, green 15%, blue 60%);
  background: -o-radial-gradient(red 5%, green 15%, blue 60%);
  background: -moz-radial-gradient(red 5%, green 15%, blue 60%);
  background: radial-gradient(red 5%, green 15%, blue 60%);
}
