首先說一下，為何要用重置樣式

除了省心之外，還有兩個好處

1.方便設計師/程式設計師發揮

白紙的感覺確實好。各種margin，padding，border的為0。。。

2.便於發現前端程式碼的遺漏

用了reset後，如果“blockquote、ol、ul、hn等語義元素在沒有賦以其他合理的樣式”，會非常扎眼（任何人都看得出來），開發者第一反應會是“臥槽忘了寫”並迅速補救。並迅速補救。但如果沒reset，瀏覽器會提供“勉強可以”的預設樣式，很多人可能就發現不了或者會想“可能就這麼設計的吧”，開發者即使意識到因為遺漏導致和設計稿不一致，出於人性弱點也可能會想“還要趕下一個專案呢先這麼湊合著吧”——由於破窗效應，這可能會導致越來越多的“湊合著吧”
