用ElementUI嘗試學(xué)習(xí)vue的時(shí)候，踩的坑。

發(fā)現(xiàn)自己在scoped樣式里面自己反復(fù)修改樣式，就是不起作用（*** 例如用個(gè)el-input組件，size="large",可是里面的字體還是小的可憐。 ），都快絕望之際，不得已用chrome的調(diào)試看下樣式到底怎么回事，原來是input的font樣式被一個(gè)叫user agent style sheet給綁架了，我設(shè)置的樣式?jīng)]有起到作用，雖然網(wǎng)上查資料，說這個(gè)user agent style sheet的優(yōu)先級(jí)很低，但是為啥很低有時(shí)候也能找到空子逆襲，把組件樣式給悄無聲息的偷掉呢？沒想明白。咨詢了google同志，原來大家為了防止這種情況，大家都用了CSSReset*, 聽起來好專業(yè)，其實(shí)就是等于自己先交了張白卷，告訴瀏覽器你能想到的我已經(jīng)想到了，別在為我著想了. 更簡(jiǎn)單的說，就是把這個(gè)reset.css的樣式表作為樣式之一先導(dǎo)入就好了。貼出我找的一個(gè),其實(shí)我也不太懂原理，只知道這么用就好了。：
