css3 flex嵌套

Question

我想知道flex是不是不能进行嵌套？大的红色框框flex:1，里面的小红色框框display:flex,中间文字部分flex:1.文字少的时候是正常的，但是多了就会超出。

文字少的时候正常

文字多的时候不会显示省略号，超出原有的宽度

html代码：

<div class="header-bg">
        <div class="sellsInf">
            <div class="avatar-wrap">
                <img class="avatar" src="../../assets/logo.png">
            </div>
            <div class="shop-detail">
                <p><span class="icon-band"></span><span class="name">周周周</span></p>
                <p class="send-time"><span>转送</span>/<span>38分钟送达</span></p>
                <div class="discount-wrap">
                    <span class="icon-discount"></span>
                    <span class="discount-detail">在线支付满在线支付满</span>
                    <span class="discount-num">5个 ></span>
                </div>
            </div>
        </div>
        <div class="bulletin">
            <span class="icon-bulletin"></span><p class="bulletin-detail">粥粥粥粥粥粥粥粥粥粥粥粥粥粥粥粥粥粥粥粥粥粥粥粥粥粥粥</p><span class="btn-go">></span>

外层容器设overflow:hidden.内层容器才会出现文字截断
