如题，就是给父元素设置上transition，那么子元素会有transition么？
在w3c规范里是否有这个的规范？能否给个链接
解决方案

CRTL+F 查"inherited"结果都是NO.
这些属性包括：
transition-propertytransition-durationtransition-timing-functiontransition-delay Propertytransition Shorthand关于继承性，文档中提到了一点
EXAMPLE 4
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.
这里提到了一个场景，如果parent指定的transition作用到的属性和child指定的transtions作用到的属性是同一个，而且parent的transtion过渡时间更长，那么就需要自己去维护transition的完成状态（完成后移除？我注）。
例如：
<div class="parent"> <div class="child"></div></div>.parent { transition: 4s text-indent;}.child{ transition: 1s text-indent;}如有错误欢迎指正。
