問(wèn)題描述

如題，就是給父元素設(shè)置上transition，那么子元素會(huì)有transition么？

在w3c規(guī)范里是否有這個(gè)的規(guī)范？能否給個(gè)鏈接

問(wèn)題解答

文檔地址： http://dev.w3.org/csswg/css-transitions/CRTL+F 查'inherited'結(jié)果都是NO.這些屬性包括：

transition-propertytransition-durationtransition-timing-functiontransition-delay Propertytransition Shorthand

關(guān)于繼承性，文檔中提到了一點(diǎn)

An example where maintaining the set of completed transitions is necessary would be a transition on an inherited property, where the parent specifies a transition of that property for a longer duration (say, transition: 4s text-indent) and a child element that inherits the parent’s value specifies a transition of the same property for a shorter duration (say, transition: 1s text-indent). Without the maintenance of this set of completed transitions, implementations could start additional transitions on the child after the initial 1 second transition on the child completes.

這里提到了一個(gè)場(chǎng)景，如果parent指定的transition作用到的屬性和child指定的transtions作用到的屬性是同一個(gè)，而且parent的transtion過(guò)渡時(shí)間更長(zhǎng)，那么就需要自己去維護(hù)transition的完成狀態(tài)（完成后移除？我注）。例如：

<p class='parent'> <p class='child'></p></p>.parent { transition: 4s text-indent;}.child{ transition: 1s text-indent;}

如有錯(cuò)誤歡迎指正。

不能。我在谷歌下試了，不能。
