Toggle开关在Firefox和Safari上看起来不错，但在Chrome上却不行

Question

我有一个拨动开关，在Safari（移动版）和Firefox中效果很好，但是在Chrome中，它看起来像html复选框……有什么想法吗？正确呈现时，这是一个非常酷的开关，但是在Chrome浏览器中，我无法正常运行。它看起来像一个拨动开关，每侧都有一个蓝色的小灯……根据开关的位置，如果将开关指向该方向，则蓝色的小灯会亮起。

我找到了解决方案！！！这是我CSS中其他地方的愚蠢语法错误……我忘记了逗号！

GOOD：

。songbuttons：hover，.pdfbutton：hover {}

坏：
