Html 将css边框作为一个元素制作SVG图标

示例：

您好，我有一个通过css添加了边框的SVG图标。我想把它做成一个元素（不是单独的svg图标和边框），这样当我停留在圆圈内或圆圈外一点时，它会改变边框和svg图标的颜色

此外，如果有任何其他方法，我可以使图标，将在小屏幕上看得很好，请让我知道。我查看了css精灵，但不知道如何使图标缩放良好（我的图标变得模糊，就像normal.png图像一样）

html:

---

如果我理解正确，您希望在

悬停

上更改整个SVG元素的颜色

如果是这样，您需要按如下方式更改CSS选择器：

#facebook：悬停{
边框：3px实心#3b5998；
}
#脸谱网：悬停路径{/*是的！谢谢你，很抱歉把这个问题说得这么糟糕，我不知道如何把它说得更好。
