我想知道以下哪个例子会更好.如果性能相同,哪一个读得更好？

示例1(重复选择器)

.helpfulCommenter, .questionTroll { color: #f00; }

.questionTroll { text-decoration: line-through; }

.questionTroll { color: #f00; text-decoration: line-through; }

.helpfulCommenter, .questionTroll { color: #f00; }

.questionTroll { text-decoration: line-through; }

要么

示例2(重复样式)

.helpfulCommenter { color: #f00; }

.questionTroll { color: #f00; text-decoration: line-through; }

.questionTroll { text-decoration: line-through; }

.helpfulCommenter { color: #f00; }

.questionTroll { color: #f00; text-decoration: line-through; }

我知道类名不是语义,这里展示的特定样式是无关紧要的.我只是想知道哪些浏览器更容易解析和实现.
