如何将时间轴中的第二个Greenstock动画更改为提前1秒开始，就像填充在画完线前1秒开始一样。
这是我的代码：
TweenLite.set(".blue-line, .yellow-line", {visibility:"visible"});
var tl = new
TimelineMax();
tl.from(".blue-line, .yellow-line", 3, {drawSVG:0, ease:Power1.easeInOut})
.to(".blue-fill, .yellow-fill", 1, {css:{opacity:1}, ease:Linear.easeIn});
TweenLite.render();
var tl = new TimelineMax();
tl.from(".blue-line, .yellow-line", 3, {drawSVG:0, ease:Power1.easeInOut})
tl.to(".blue-fill, .yellow-fill", 1, {css:{opacity:1}, ease:Linear.easeIn} , "-=1");
在"to"方法的末尾添加"-=1"，则交错将起作用。
