我无法在我的网站上使用GSAP的Draggable脚本。我尝试从the tutorial here
实现最基本的我已经读过documentation和一些introductory material，但我无法使其正常工作。
使用javascript，HTML和CSS制作SVG对我来说是新手，所以如果我错过了重点，请多多包涵。
故障排除/注意事项：
CSS
body {
margin:0;
background: #333;
text-align:center;
color:#ddd;
font-family: Signika Negative, Asap, sans-serif;
}
.icon {
cursor: grab;
position:absolute;
top:0px;
}
svg {
display:block;
position:relative;
width:400px;
background:#1d1d1d;
margin:20px auto;
}
JavaScript
<script type="text/javascript">
Draggable.create(".icon");
</script>
HTML
