Hi, I want to make dark night with twinkling stars. However, all stars will twinkle together. I mean they will become bright and dark at same time. How can I make them twinkle separately. Thanks for the help!!!! Following content is my code. // ----- create star ----- function createStar(){ var tmpStar = document.createElement('figure') tmpStar.className = "star"; tmpStar.style.top =100*Math.random()+'%'; tmpStar.style.left = 100*Math.random()+'%'; document.getElementById('sky').appendChild(tmpStar); } function myRandom(){ return 100*Math.random(); } var i = 40; while(i){ createStar(); i-=1; } // ----- star twinkling ----- var starTest = document.getElementsByClassName("star"); var starTween = new TimelineMax({repeat:-1}); starTween.add(TweenMax.to(starTest,0.8,{opacity:1,delay:0})); starTween.add(TweenMax.to(starTest,0.5,{opacity:0,delay:1}));
