使div每次都转到下一列，它的值可以被5整除

.parent-container {
  display: flex;
  flex-wrap: wrap;
}

<div class="parent-container">
  <div class="child">1</div>
  <div class="child">2</div>
  <div class="child">3</div>
  <div class="child">4</div>
  <div class="child">5</div>
  <div class="child">6</div>
  <div class="child">7</div>
  <div class="child">8</div>
  <div class="child">9</div>
  <div class="child">10</div>
  <!-- 继续添加更多的div元素 -->
</div>

const divs = document.querySelectorAll('.child');
const parent = document.querySelector('.parent-container');
const columnCount = 5; // 列数

divs.forEach((div, index) => {
  const columnIndex = index % columnCount;
  const column = parent.children[columnIndex];
  column.appendChild(div);
});
