法實(shí)現(xiàn)標(biāo)題欄的動(dòng)態(tài)顯示/隱藏？

大部分 css 都可以作用于 svg 元素，只需要像寫(xiě)普通 css 一樣，把選擇器寫(xiě)對(duì)就行了。如果需要的話，可以給 path 加上 class 或者 id 屬性。不光是 css 動(dòng)畫(huà)，就連 fill 這樣 svg 屬性都可以都可以通過(guò) css 來(lái)指定。但有時(shí)候我們想要一些效果需要更改圖形的結(jié)構(gòu)，比如提主貼出來(lái)的圖，是一個(gè)對(duì)話框加一個(gè)外環(huán)，如果我想讓對(duì)話框翻轉(zhuǎn)的話，就要把它單獨(dú)拿出來(lái)做一個(gè) path 元素了。這時(shí)候就需要設(shè)計(jì)師的協(xié)助（如果提主自己會(huì)手改 svg 的話也可以）。http://jsfiddle.net/dw7akdg1/
