如何仅使用CSS将复选框与标签对齐

<div class="checkbox-container">
  <input type="checkbox" id="checkbox">
  <label for="checkbox">标签</label>
</div>

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

.checkbox-container input[type="checkbox"] {
  position: relative;
  appearance: none;
  -webkit-appearance: none;
  width: 16px;
  height: 16px;
  border: 1px solid #ccc;
  border-radius: 3px;
  outline: none;
  margin-right: 5px;
}

.checkbox-container input[type="checkbox"]::before {
  content: "";
  position: absolute;
  top: 2px;
  left: 2px;
  width: 10px;
  height: 10px;
  background-color: #fff;
  border-radius: 2px;
  transition: background-color 0.3s ease;
}

.checkbox-container input[type="checkbox"]:checked::before {
  background-color: #007bff;
}

.checkbox-container label {
  margin: 0;
  padding: 0;
}
