如何在CSS中将一个文本和一个矩形(带有一些文本)放在同一行？

<span>
  文本
  <span class="rectangle">矩形</span>
</span>

.rectangle {
  display: inline-block;
  width: 100px;
  height: 20px;
  background-color: #ccc;
  text-align: center;
  line-height: 20px;
}

<div class="container">
  文本
  <div class="rectangle">矩形</div>
</div>

.container {
  overflow: hidden;
}

.rectangle {
  float: left;
  width: 100px;
  height: 20px;
  background-color: #ccc;
  text-align: center;
  line-height: 20px;
}

<div class="container">
  <span>文本</span>
  <div class="rectangle">矩形</div>
</div>

.container {
  display: flex;
  align-items: center;
}

.rectangle {
  width: 100px;
  height: 20px;
  background-color: #ccc;
  text-align: center;
  line-height: 20px;
}
