Flex和inline-flex都将Flex布局应用于容器的子容器。带有display:flex的容器行为类似于块级元素本身，而display:inline-flex使容器行为类似于内联元素。

显示:inline-flex不会使伸缩项目内联显示。它使伸缩容器内联显示。这是display: inline-flex和display: flex之间的唯一区别。类似的比较可以在display: inline-block和display: block之间进行，以及几乎任何其他具有内联对应项的显示类型

对伸缩物品的效果绝对没有区别;无论Flex容器是块级还是内联级，Flex布局都是相同的。特别是，伸缩项本身总是表现得像块级盒子(尽管它们确实具有内联块的一些属性)。不能内联显示伸缩项;否则你就没有伸缩布局。

It is not clear what exactly you mean by "vertically align" or why exactly you want to display the contents inline, but I suspect that flexbox is not the right tool for whatever you are trying to accomplish. Chances are what you're looking for is just plain old inline layout (display: inline and/or display: inline-block), for which flexbox is not a replacement; flexbox is not the universal layout solution that everyone claims it is (I'm stating this because the misconception is probably why you're considering flexbox in the first place).

块布局和内联布局之间的区别超出了这个问题的范围，但最突出的一个是自动宽度:块级盒子水平拉伸以填充其包含的块，而内联级盒子收缩以适应其内容。事实上，仅仅因为这个原因，你几乎永远不会使用display: inline-flex，除非你有一个很好的理由内联显示你的flex容器。

您需要更多的信息，以便浏览器知道您想要什么。例如，需要告诉容器的子容器“如何”伸缩。

更新的小提琴

我添加了#wrapper > * {flex: 1;保证金:汽车;并将inline-flex更改为flex，您可以看到元素现在如何在页面上均匀地分开。

您可以内联显示伸缩项，前提是您的假设是基于首先需要灵活的内联项。使用flex意味着一个灵活的块级元素。

最简单的方法是使用flex容器，并将其子容器设置为flex属性。在代码方面，它看起来像这样:

.parent{
   display: inline-flex;
}

.children{
   flex: 1;
}

Flex: 1表示比率，类似于元素宽度的百分比。

您可以摆弄浏览器控制台，在flex和内联flex之间更改容器元素的显示。
