Flexbox顺风：无法让子元素的宽度调整内容

问题描述

我有此代码：

<div class = "flex-none   flex-col  bg-gray-500   border border-black rounded   rounded p-5 ">
    <div class=" border w-auto  bg-gray-700 flex-none  flex-col content-start  justify-start  ">
        <div
                class = "border border-red-200 w-auto inline-block flex flex-row content-start
                    justify-start bg-gray-900 cursor-pointer  hover:bg-gray-700
               border rounded   border-black p-2 mt-2   ">
            A

        </div>

        <div
                class = "border border-red-200 w-auto inline-block flex flex-row content-start
                    justify-start bg-gray-900 cursor-pointer  hover:bg-gray-700
               border rounded   border-black p-2 mt-2   ">
            B

        </div>

        <div
                class = "border border-red-200 w-auto inline-block flex flex-row content-start
                    justify-start bg-gray-900 cursor-pointer  hover:bg-gray-700
               border rounded   border-black p-2 mt-2   ">
            C

        </div>
    </div>
</div>

它看起来像这样：

我希望它像这样调整宽度到内容大小：

解决方法

在父容器上使用inline-flex而不是flex
