重复的CSS类？

Question

甚至不确定我应该在哪里开始调试此问题，但由于某些原因，我的所有CSS类似乎都在重复。我附上一张图片作为参考，但除此之外;我不知道从哪里开始寻找。我用Yeoman AngularJS生成器创建了我的项目。没有Sass或LESS。有人有主意吗？

编辑：在为生产构建缩小文件之前，不会复制CSS类。除了在线发布我的Gruntfile.js之外，我不知道该怎么做？看起来有点矫枉过正，但我​​不确定在哪里看。

Answer 1

我猜这个文件只有一条非常长的行，因为它被缩小（以避免缓存文件也有唯一的前缀）。只需打开该文件并计算您可以找到此声明的次数。

Answer 2

我在你的grunt文件中可以看到的唯一可能是问题的是你的cssmin任务。您注释掉了指定根文件夹的选项。我假设cssmin不再仅仅查看您的应用程序，但在根级别，包括.tmp，dist等。尝试取消注释该选项，看看是否能解决您的问题
