我正在使用带有twitter-bootstrap的rails on rails3创建网站 我从官方网站下载了bootstrap.css并进行了设置。
它显示一切整洁但超链接的颜色 我想要它是蓝色的，但所有的超级链接都用黑色显示.... 谁能告诉我为什么？我无法弄明白为什么
我的代码是

答案 0 :(得分：3)
默认情况下，Bootstrap链接为蓝色。大量的CSS文件堆栈中的某个地方是一个规则集，看起来像这样的东西：
a { color:black; }
如果您使用Firefox与Firebug或Chrome开发者工具，您可以检查任何锚元素，并查看违规规则集的确切位置。
或者，您可以将此规则集放在要加载的最后一个CSS文件的底部：
a { color:blue; }
