Prevent flexbox display in a new line

Question

I have a parent and two main children. The first child has two elements with fixed width and height. The second child has some text and when I resize text is shown or hidden in response to page size. But when I resize at a certain point the two elements of the first child insted of staying inline they go one above the other. How can I prevent this?

所以在第二张图片中，两个元素是一个在另一个之上，我不想要这个。

html

<div class="parent-div">
  <div class="icon-div">
      <div>a</div>
      <div>a</div>
    </div>
  <div class="text-div">This is text I'd like to truncate when space doesn't permit</div>
</div>

css

.parent-div {
    display: -webkit-flex;
    display: -moz-flex;
    display: flex;
}

.text-div {
    white-space: nowrap;
    overflow: hidden;
    text-overflow: hidden;    
    min-width: 0;
}

.icon-div {
    -webkit-flex: 1;
    -moz-flex: 1;
    flex: 1;
}

.icon-div div {
    display:inline-block;
    border: 1px solid #ccc;
    width:40px;
    height:40px;
}

不要让你的.icon-div缩水 ( flex: 1 0 auto);

.icon-div {
    flex: 1 0 auto;
}

设置：white-space:nowrap有一个不幸的副作用，text-div就是icon-div当屏幕变得太小时，文本会跑到占用的空间中。
