CSS3圈悬停

Question

我在使用CSS3创建此效果时遇到问题。我知道这是可能的，但我无法弄清楚如何做到这一点。我们用Javascript（https://vimeo.com/104875594）创建了它。你们中有谁可以帮忙解决这个问题吗？

问题是，当您从圆圈中的左侧移动到右侧时，旋转动画将向后运行，因为您的主要位置位于顶部。我们需要360度左右，而不仅仅是180度。

感谢。

我可以看到你是新来的，所以请在将来提供一些代码和jsfiddle，我们在这里帮助你不要为你工作。

使用Pure CSS，您可以在fullscreen

中执行此操作

不知道这是否正是您正在寻找的东西，但它可以作为如何旋转360度左右的一个很好的参考。你可以使用

transform：rotate（-1turn）; //或顺时针转动正数

以下是整个例子。
