在我的太阳系系统模型中,当您点击“切换轨道”时,它会显示所有熟悉的行星地球的轨道,但是您注意到,该环不在该星球的中间,仅在其外部,如何使其成为所以会在中间？

解决方法
您将.earth线静态地放在.earth-orbit上,所以调整.earth和.moon的边距是一个合乎逻辑的解决方案.
另一方面,让我们开始思考.如果我们把.earth线作为单独的div呢？喜欢这个：
<div class="earth-lines">
</div>
<div class="earth-orbit ">
<div class='moon-orbit'>
<img class="moon" src="http://space-facts.com/wp-content/uploads/moon-transparent.png" />
</div>
</div>
而.earth-line的CSS将如下所示：
.earth-lines {
display: none;
border-width: 1px;
border-style: solid;
border-color: white;
border-radius: 50%;
position: absolute;
height: 226px;
width: 226px;
top: 50%;
left: 50%;
margin-left: -113px;
margin-top: -113px;
}
最后一件事是调整JavaScript：
<script>
$(document).ready(function() {
$("button").click(function() {
$('.earth-lines').toggle();
});
});
</script>
在这种情况下,它将被切换,并将看起来只是你想要的方式.这是一个小提琴：http://jsfiddle.net/x3ybjd0f/1/
附：奇妙的想法和实现,我喜欢它;)
UPDATE
如何解决太阳
在你的代码中,你有< img class =“sun”src =“5.png”>
根据您的意见,图片的链接是http://toms-storage.tk/5.png
所以正确的代码就是< img class =“sun”src =“http://toms-storage.tk/5.png”>
