Vue，如果我选择了一个选项，如何获得空行？

<template>
  <div>
    <select v-model="selectedOption">
      <option value="option1">Option 1</option>
      <option value="option2">Option 2</option>
      <option value="option3">Option 3</option>
    </select>
    <br> <!-- 插入空行 -->
    <p>You selected: {{ selectedOption }}</p>
  </div>
</template>

<template>
  <div>
    <select v-model="selectedOption">
      <option value="option1">Option 1</option>
      <option value="option2">Option 2</option>
      <option value="option3">Option 3</option>
    </select>
    <div class="empty-space"></div> <!-- 插入空行 -->
    <p>You selected: {{ selectedOption }}</p>
  </div>
</template>

<style>
.empty-space {
  height: 20px; /* 设置空行的高度 */
}
</style>

<template>
  <div>
    <select v-model="selectedOption">
      <option value="option1">Option 1</option>
      <option value="option2">Option 2</option>
      <option value="option3">Option 3</option>
    </select>
    {{ emptyLine }} <!-- 插入空行 -->
    <p>You selected: {{ selectedOption }}</p>
  </div>
</template>

<script>
export default {
  data() {
    return {
      selectedOption: ''
    };
  },
  computed: {
    emptyLine() {
      return '\n'; // 返回换行符
    }
  }
};
</script>
