CSS3 Notes: -webkit-box-reflect实现倒影的实例

<stop offset="0%" style="stop-color:yellow"/>
<stop offset="100%" style="stop-color:red"/>
</linearGradient>
<linearGradient id="b" x1="0" y1="0" x2="0" y2="100%">
<stop offset="0%" style="stop-color:rgba(255,255,255,0)"/>
<stop offset="100%" style="stop-color:rgba(255,255,255,1)"/>
</linearGradient>
<mask id="c" x="0" y="0" width="1" height="1">
<rect x="0" y="0" width="100%" height="100%" style="fill:url(#b)" />
</mask>
</defs>
<rect x="0" y="0" width="200" height="200" style="fill:url(#a);" mask="url(#c)">
</svg>

canvas例子部分代码如下

var canvas = document.getElementById('canvas'),
ctx = canvas.getContext('2d');
var linearGradient1 = ctx.createLinearGradient(0,0,0,200);
linearGradient1.addColorStop(0,"red");
linearGradient1.addColorStop(1,"yellow");
var linearGradient2 = ctx.createLinearGradient(0,0,0,200);
linearGradient2.addColorStop(0,"transparent");
linearGradient2.addColorStop(1,"#ffffff");
ctx.fillStyle = linearGradient1;
ctx.fillRect(0,0,200,200);
ctx.globalCompositeOperation = 'destination-out';
ctx.fillStyle = linearGradient2;
ctx.fillRect(0,0,200,200);

以上便是倒影实现的各种方法，对比之下用css3的-webkit-box-reflect实现最简单效果也好。希望对大家的学习有所帮助，也希望大家多多支持软件开发网。
