我今天也遇到了这个问题，最后发现是因为站点更新了。现在你可以访问这个网站找到需要的文件了。
fonts.googleapis.com一种办法是用这个域名代替你原来的字体库地址；
另一种是下载下来之后本地引入。
下面是你需要的资源：

你可以复制上面的代码，然后保存为.css文件。
a的作用是链接，点击<a></a>之间的内容，页面会跳转到链接的地址。直接设置它的颜色，比如，例子中a{color:#000}，意思是<a></a>之间的内容显示为黑色，如果不设置的话，浏览器默认的a链接的颜色是蓝色；
a:hover属于css，它设置了当鼠标悬浮在链接内容之上时，链接内容的样式，比如，例子中a:hover{ color:#F00}，它设置了当鼠标悬浮在该链接内容上时，链接内容变成红色。
扩展资料：总结几个a的伪类：
a:link 英文link就是链接的意思，代表当一段文本为链接时的属性。
a:visited 英文visited就是访问过的意思，代表这段文本被点击之后的属性。
a:hover 英文hover就是悬停的意思，代表鼠标指针放在这个链接上时的属性。
a:active 英文active就是有效的、快速的意思，代表鼠标按下时一瞬间的属性。
一般最常用的方法是a {CSS属性} a后面什么也没有，代表一次定义这四个属性，然后根据需要再定义其中某个属性就可以了，最常用的是a:hover {CSS属性}
