如何使省略号在flex容器中工作？

Question

在display: flex上没有.container的情况下，减小容器大小时文本会正确地截断。

但是绿色的块和文本不再相邻了，因为容器没有display: flex。当我将其添加到容器中时，绿色块和文本已正确对齐，但文本不再被截断（省略了省略号）。

我如何使用flex来确保块和文本对齐，同时在动态宽度容器中将文本用省略号截断？

my example codepen

body {
  padding: 20px;
}

.container {
  display: flex;
}

.block {
  width: 25px;
  height: 25px;
  padding: 10px;
  background-color: yellowgreen;
  display: flex;
  align-items: center;
  justify-content: center;
  margin-right: 20px
}

.text {
  display: flex;
}

.truncate {
  flex: 1;
  min-width: 0;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
  font-size: 20pt;
}

<div class="container">
  <div class="block">B</div>
  <div class="text">
    <div class="truncate">
      3. This is a long string that is OK to truncate please and thank you
    </div>
  </div>
</div>

您的带省略号的弹性项目必须能够收缩到内容的宽度以下。有关完整的详细信息，请参见我的回答：Why don't flex items shrink past content size?

body {
  padding: 20px;
}

.container {
  display: flex;
  border: 1px dashed red; /* demo */
}

.block {
  flex: 0 0 25px;  /* flex-grow, flex-shrink, flex-basis */
                   /* set flex-shrink to 0 to prevent item from shrinking below 25px */
  padding: 10px;
  background-color: yellowgreen;
  display: flex;
  align-items: center;
  justify-content: center;
  margin-right: 20px;
}

.text {
  display: flex;
  min-width: 0; /* allow item to shrink below content size */
}

.truncate {
  flex: 1;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
  font-size: 20pt;
  background-color: yellow; /* demo */
}

<div class="container">
  <div class="block">B</div>
  <div class="text">
    <div class="truncate">
