Aligning two elements to the center

Issue

How can I make "question" vertically center-aligned with "answer-text", but not with "submit-answer-button"?

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

.answer-container {
  display: flex;
  justify-content: center;
}

  <div class="question-container">
    <div id="question">6 x 2</div>
    <div class="answer-container">
      <input type="text" id="answer-text">
      <button id="submit-answer-button" onclick="submitAnswer()">Submit</button>
    </div>
  </div>

Solution

If you don't want to change the html, you can use grid-template-columns: subgrid; to .answer-container. For example, like this:

.question-container {
  display: inline-grid;
  grid-template-columns: 1fr auto;
}

#question {
  text-align: center;
  white-space: nowrap; /* optional */
  border: dashed 1px red; /* testing */
}

.answer-container {
  display: grid;
  grid-column: span 2;
  grid-template-columns: subgrid;
}

.answer-container input {
  min-width: 0; /* srinking */
}

/* just for centering */
body {
  display: grid;
  min-height: 100dvh;
  margin: 0;
  place-items: center;
}

<div class="question-container">
  <div id="question">6 x 2</div>
  <div class="answer-container">
    <input type="text" id="answer-text">
    <button id="submit-answer-button">Submit</button>
  </div>
</div>
