https://fivosm.github.io/在IE上测试，Firefox，Chrome工作正常，a：link的背景是红色的。在边缘，虽然背景不是红色的，直到我把鼠标悬停在它上面。
我不知道从哪里开始，我的谷歌搜索没有显示与我的问题相关的任何内容。 这是我的粘贴链接，以防格式再次混乱

定义 a 的背景。此外，您还有 a：visited样式将背景颜色设置为 #7b77ff。如果您不需要它作为链接按钮样式，请将其删除。
a{
background-color: #f44336;
...
}
a:visited {
background-color: #7b77ff;
}
就我而言，您所有按钮的背景在Chrome，FireFox和Edge中都可以正常工作(请参阅：它们都以红色背景显示(，无论如何...
您似乎没有定义
a {
background-color: #f44336;
}
相反，您使用的是:link和:visited
您是否可能已经在 Edge 中使用了链接，并且它正在使用您为:visited设置的background-color？如果您希望它们不更改，请删除:visitedcss 中的background-color
看起来边缘不喜欢模糊超过 4px 的文本阴影。
替换这个：
.shadow {
text-shadow: 2px 2px 10px #d3d3d3;
}
有了这个：
.shadow {
text-shadow: 2px 2px 4px #d3d3d3;
}
修复了一切。 谢谢。
