如何获得每行显示三个项目并均匀分布的布局soi？

<style>
.container {
  display: flex;
  flex-wrap: wrap;
}

.item {
  flex-basis: 33.33%;
}
</style>

<div class="container">
  <div class="item">项目1</div>
  <div class="item">项目2</div>
  <div class="item">项目3</div>
  <div class="item">项目4</div>
  <div class="item">项目5</div>
  <div class="item">项目6</div>
  <!-- 其他项目 -->
</div>

<style>
.container {
  display: grid;
  grid-template-columns: repeat(3, 1fr);
}

.item {
  grid-column: span 1;
}
</style>

<div class="container">
  <div class="item">项目1</div>
  <div class="item">项目2</div>
  <div class="item">项目3</div>
  <div class="item">项目4</div>
  <div class="item">项目5</div>
  <div class="item">项目6</div>
  <!-- 其他项目 -->
</div>
