Css Webkit梯度固定度？

我用WebKit渐变组合了这个CSS3背景：

background-image: -webkit-gradient(linear, right top, left bottom, 
    color-stop(0.01, #B601B3),
    color-stop(2%, #9106D3),
    color-stop(4%, #6B16EC),
    /* [...](rainbow colors) */
    color-stop(96%, #2850FE),
    color-stop(98%, #1175F7),
    color-stop(1.0, #039BE5));

这很好（在Chrome和Safari中，正如预期的那样），但每次页面“变长”时，它都会调整大小，不会以相同的程度移动，而且渐变经常会被拖得很长

---

有没有办法使一个线性梯度在一个固定的方向上“前进”？你能在moz linear gradient中做同样的事情吗？

我最后就是这样做的，支持所有现代浏览器（Safari、Chrome、Firefox和Opera）：

这是未来搜索者的完美彩虹渐变！：）
