首先说一下,为何要用重置样式
除了省心之外,还有两个好处
1.方便设计师/程序员发挥
白纸的感觉确实好。各种margin,padding,border的为0。。。
2.便于发现前端代码的遗漏
用了reset后,如果“blockquote、ol、ul、hn等语义元素在没有赋以其他合理的样式”,会非常扎眼(任何人都看得出来),开发者第一反应会是“卧槽忘了写”并迅速补救。并迅速补救。但如果没reset,浏览器会提供“勉强可以”的默认样式,很多人可能就发现不了或者会想“可能就这么设计的吧”,开发者即使意识到因为遗漏导致和设计稿不一致,出于人性弱点也可能会想“还要赶下一个项目呢先这么凑合着吧”——由于破窗效应,这可能会导致越来越多的“凑合着吧”

html{font-size:62.5%}
原因:1rem = 16px
